Secret Missions

Starting a Secret Mission

Secret Missions in The Wonderful 101 are optional Missions within levels that can be found by exploring side areas, backtracking to previously completed areas, or by performing specific actions that will trigger one's appearance.

Secret Missions can be found in two forms: Secret Missions that function like regular Missions, in that they're automatically started by simply entering the Mission's area once they become available, and Kahkoo-regah Secret Missions, which are special challenge Missions that can only be started by finding a GEATH-Circle and using the Wonder-Liner to transform it into a portal, which can send you into the Kahkoo-regah where a Secret Mission will begin. Kahkoo-regah Secret Missions feature unique mechanics and increased difficulty, and they award a Wonderful Figure for their completion.

For full details on the mechanics of Kahkoo-regah Secret Missions, see the Kahkoo-regah page.

Completing all Secret Missions on all 5 Difficulty levels is the objective of the Operation Annihilation Bottle-Cap.

It's important to make note of the fact that Kahkoo-regah Secret Missions are exclusive to the Normal, Hard, and 101% Hard Difficulty levels, and that they are absent on Easy and Very Easy.
This is relevant when trying to earn the Operation Annihilation Bottle-Cap for completing all Secret Missions, as any level whose only Secret Mission is a Kahkoo-regah effectively does not have any Secret Missions on Easy and Very Easy, meaning it's not required to play these levels on these Difficulties to achieve 100% completion of the game.

Note: Because Kahkoo-regah Secret Missions are absent on Easy and Very Easy, any Mission (secret or otherwise) that appears after a Kahkoo-regah in a level has their Mission number lowered by one on these Difficulty levels. All Missions are named by their Normal/Hard/101% Hard numbers on this Wiki by default, however, any Mission whose number would change on Easy and Very Easy has their Mission number underlined. On desktop, you can hover over this underlined text to view a tooltip displaying the Mission's new number on Easy and Very Easy.

Secret Mission Locations

Operation 000 Prologue

Secret Mission 006 (Kahkoo-regah)

After completing Mission 005, a Kahkoo-regah will appear inside the bus under you. The only way to get inside the bus is to use Unite Hammer to break open the roof hatch, meaning it's not normally possible to access this Kahkoo-regah during your first playthrough of the level.

Normal Reward: Wonderful Figure No.026 Wonder-Professor

Hard Reward: Wonderful Figure No.051 Wonder-Rabbit

101% Hard Reward: Wonderful Figure No.001 Wonder-Red

This Kahkoo-regah isn't reachable until Unite Hammer is unlocked in 003-A

Operation 001-A

Secret Mission 005

After Mission 004, backtrack across the now broken bridge to the previous area to start Secret Mission 005. Alternatively, entering the pipe in the nearby canal will cause you to exit directly into the Secret Mission.

Secret Mission 009

After Mission 008 (rescuing citizens from a fire), backtrack to the football field to start Secret Mission 009.

Secret Mission 011 (Kahkoo-regah)

You'd have to be pretty dense to miss the Kahkoo-regah P-Star gives you a tutorial on

A Kahkoo-regah appears in the middle of the road after Mission 010 is completed (the first encounter with a Diedough-Goo.)
P-Star provides a tutorial on Kahkoo-regah Secret Missions the first time you encounter this one.

Normal Reward: Wonderful Figure No.049 Wonder-Oracle

Hard Reward: Wonderful Figure No.082 Wonder-Cellphone

101% Hard Reward: Wonderful Figure No.003 Wonder-Green

Operation 001-B

Secret Mission 005 (Kahkoo-regah)

After Mission 004 (the first encounter with You-Houghs and Wonder-Green,) a Kahkoo-regah will appear in the middle of the road back at the beginning of the area, where you landed after battling the Gah-Goojin.

While technically this Kahkoo-regah can be entered any time after Mission 004 and before entering Blossom Stadium at the end of the level, it's highly recommended to complete it immediately after Mission 004, as entering and exiting the Kahkoo-regah after Mission 006 is completed can cause glitches in the level.

Normal Reward: Wonderful Figure No.073 Wonder-Science

Hard Reward: Wonderful Figure No.099 Wonder-Camera

101% Hard Reward: Wonderful Figure No.002 Wonder-Blue

Operation 002-A

Secret Mission 006 (Kahkoo-regah)

After Mission 005, a Kahkoo-regah will appear back at the beginning of the area, where you landed after battling Prince Vorkken.

Normal Reward: Wonderful Figure No.027 Wonder-Magician

Hard Reward: Wonderful Figure No.072 Wonder-Automobile

101% Hard Reward: Wonderful Figure No.004 Wonder-Pink

Operation 002-B

Secret Mission 004

After Mission 003 (the first encounter with a Nyerk,) backtrack to the Mission 001 area to start Secret Mission 004

Secret Mission 005 (Kahkoo-regah)

This hidden platform is actually perfectly visible during the earlier Nyerk intro cutscene (Pic)

In the area after Mission 003, the Wonder-Liner can be extended directly up into the air using the billboard: if you have at least 100 Members, doing so will form a Unite Chain that allows you to reach a hovering platform offscreen where a Kahkoo-regah can be found.

Note: 100 Members are required to form a Unite Chain here, and the platform (and thus the Kahkoo-regah) is impossible to reach without using Unite Chain. Because of the low number of citizens available at this point in the level, it may not be possible to reach 100 members during your first playthrough unless you've either recruited every Minor Wonderful One available at this point, or recruited some enemies from an earlier mission.

Normal Reward: Wonderful Figure No.079 Wonder-Radio

Hard Reward: Wonderful Figure No.090 Wonder-Locomotive

101% Hard Reward: Wonderful Figure No.107 Wonder-Scarf

Operation 003-A

Secret Mission 001 (Kahkoo-regah)

After exiting back out to the exterior of the first shuttle, move down toward the bottom of the screen to get on top of the shuttle's fuselage, where a Kahkoo-regah can be found.

Normal Reward: Wonderful Figure No.022 Wonder-Judo

Hard Reward: Wonderful Figure No.036 Wonder-Pâtissière

101% Hard Reward: Wonderful Figure No.005 Wonder-Yellow

Operation 003-B

Secret Mission 006 (Kahkoo-regah)

Defeat all the optional enemies that spawn inside of the passenger area of the final shuttle to make a Kahkoo-regah appear at the end of the area.

Normal Reward: Wonderful Figure No.015 Wonder-Socho

Hard Reward: Wonderful Figure No.061 Wonder-Matador

101% Hard Reward: Wonderful Figure No.108 Wonder-Gramps

Operation 004-A

Secret Mission 003 (Kahkoo-regah)

Try to ignore P-Star

If Mission 002 is completed without going underwater, a Kahkoo-regah will appear on the platform just before the Mission. The enemies spawn at the bottom of the water, but if you just wait a few moments they'll swim up to the surface, and you can start fighting them normally. Once the Kahkoo-regah appears, you can go underwater and it won't disappear.

You'll fail this requirement if you sink into the water even slightly, so avoid using Unite Hammer, Unite Tombstone, or a Size 100 version of any other attacking Unite Morph to prevent yourself from going underwater at all until Mission 002 is completed. Should you fail to make the Kahkoo-regah appear, immediately selecting the RETRY option from the pause menu will put you back at a nearby checkpoint just before Mission 002.

Normal Reward: Wonderful Figure No.039 Wonder-Nurse

Hard Reward: Wonderful Figure No.094 Wonder-Medicine

101% Hard Reward: Wonderful Figure No.006 Wonder-White

Secret Mission 007

After using Unite Claw to open the doors to the first set of pipes in the level, backtrack to the Mission 005 area to begin Secret Mission 007.

Operation 004-B

Secret Mission 003 (Kahkoo-regah)

First, enter the underwater side of the outdoor part of the level using the hidden warp pipe found by jumping off the bottom corner of the Mission 002 area (the first encounter with an Ankho.)

From there, go up and hug the wall while staying underwater until you reach the upper corner with citizens, and stand in front of the short section of wall that's underwater: doing this will make a Kahkoo-regah appear back where you landed after battling Prince Vorkken.
A faster but less reliable method to trigger the Kahkoo-regah is to repeatedly run and dodge into the water from outside, specifically at the corner where the water meets the elevator wall, as it's barely possible to touch the trigger from outside.

Normal Reward: Wonderful Figure No.055 Wonder-Prince

Hard Reward: Wonderful Figure No.034 Wonder-Shopping

101% Hard Reward: Wonderful Figure No.110 Wonder-Future

Operation 005-A

Secret Mission 002

First, in the outdoor jungle section of the level, use Unite Claw to climb up to the ledge behind the waterfall, and use Unite Hammer to open up a volcanic tunnel that leads you to a hidden side area.

From here, walk to the left side of the hidden area to begin Secret Mission 002.

Secret Mission 006

After Mission 005 (Where Dooras and Wonder-Black are encountered for the first time) backtrack to the Mission 004 area to begin Secret Mission 006.

Secret Mission 007 (Kahkoo-regah)

A Kahkoo-regah can be found at the very top of the spinning drill statue. There's an opening at the top of the drill that can be entered to easily get on the statue's hands, and from there Unite Claw can be used to climb up to the statue's head where the Kahkoo-regah can be found.

Normal Reward: Wonderful Figure No.009 Wonder-Beetle

Hard Reward: Wonderful Figure No.008 Wonder-Clean

101% Hard Reward: Wonderful Figure No.007 Wonder-Black

Operation 005-B

Secret Mission 007 (Kahkoo-regah)

Use Unite Hand to light the four torches surrounding the orb pedestal on fire to make a Kahkoo-regah appear on the path.

Note: the Kahkoo-regah must be completed before you start backtracking with the statue, as the ensuing collapse of the area renders this Kahkoo-regah inaccessible.

Normal Reward: Wonderful Figure No.066 Wonder-Voodoo

Hard Reward: Wonderful Figure No.085 Wonder-Padlock

101% Hard Reward: Wonderful Figure No.109 Wonder-Daddy

Secret Mission 008

Stick it to the Diedough-Goos!

After placing the orb on its pedestal to free the statue, backtrack to and stand in the center of the Mission 005 spike trap arena to begin Secret Mission 008.

Normally, it's far more convenient to start this Secret Mission after also recruiting the statue and backtracking with it. However, if you're trying to earn a Pure Platinum score on the level's final Mission (which normally has to be completed after the Secret Mission without any checkpoints in between,) it can be a good idea to complete the Secret Mission immediately after placing the orb, that way your completion of the Secret Mission will be saved by a checkpoint once you finally recruit the statue and backtrack with it, leaving only the final Mission to complete by itself.

Operation 006-A

Secret Mission 006 (Kahkoo-regah)

Not the worst secret in the game, but it's up there

After Mission 005 (the first encounter with a Deah-Kani,) you can extend the Wonder-Liner from bottom right edge of the mission area to form a Unite Chain, allowing you to reach a platform hidden offscreen with citizens and various collectibles. Note that using Unite chain is actually required here, as otherwise an invisible wall blocks you from falling off the main part of the level.

But you're not done yet: from this hidden platform, extend the Wonder-Liner to the bottom left to form another Unite Chain that will allow you to reach a second hidden platform, on which you can find a Kahkoo-regah.

Normal Reward: Wonderful Figure No.069 Wonder-Treasure

Hard Reward: Wonderful Figure No.095 Wonder-Plane

101% Hard Reward: Wonderful Figure No.103 Immorta

Secret Mission 008

After completing Mission 007 (the Orgons,) backtrack to the Mission 005 area to begin Secret Mission 008.

If you're trying to earn a Pure Platinum score on this Secret Mission, it can be a good idea to progress slightly down the main path of the level after Mission 007 to trigger a checkpoint and then backtrack from there, as otherwise attempting Secret Mission 008 immediately after Mission 007 will force you to redo Mission 007 every time you need to retry. If you're on Normal difficulty or above, you can enter and exit the nearby Kahkoo-regah to use as a checkpoint once you're satisfied with Secret Mission 008.

Operation 006-B

Secret Mission 005 (Kahkoo-regah)

A Kahkoo-regah will appear on the starting position of the main part of the level (after Mission 003) if you light the four surrounding torches on fire. However, there are no sources of fire immediately nearby, meaning you'll have to go across the freezing water to ignite your Unite Hand on a fire over there, and then carefully platform back across the freezing water without ever putting it away in order to light these torches.

Normal Reward: Wonderful Figure No.056 Wonder-Pixie

Hard Reward: Wonderful Figure No.017 Wonder-Vegetable

101% Hard Reward: Wonderful Figure No.104 Wonder-Red (Emeritus)

Operation 007-A

Secret Mission 004 (Kahkoo-regah)

After completing Mission 003 (the Gehdowns,) a Kahkoo-regah will appear on one of the cell platforms back at the start of the level.

Normal Reward: Wonderful Figure No.025 Wonder-Yeti

Hard Reward: Wonderful Figure No.057 Wonder-Dancer

101% Hard Reward: Wonderful Figure No.102 Chewgi

Secret Mission 007

After using Unite Hammer to strike the platform that must be pulled down using Unite Whip, return to the Mission Mission 006 platform to begin Secret Mission 007.

Operation 008-A

Secret Mission 005

After completing Mission 004 (at Blossom City Elementary School,) backtrack to the Mission 002 area to begin Secret Mission 005.

Secret Mission 008 (Kahkoo-regah)

After riding the fan platform's updraft up to the end of the level, a Kahkoo-regah will appear all the way back near Blossom City Elementary School. Be careful to not actually land on the end level platform after riding the updraft however, as a one-way invisible wall prevents you from jumping back off, and the game autosaves as soon as you land, trapping you there.

Normal Reward: Wonderful Figure No.076 Wonder-Jungle

Hard Reward: Wonderful Figure No.048 Wonder-Ice Cream

101% Hard Reward: Wonderful Figure No.101 Prince Vorkken

Operation 008-B

Secret Mission 002 (Kahkoo-regah)

After dropping down from Blossom Stadium, a Kahkoo-regah can be found by climbing all the way to the top of the climbing wall. You can also just land on it as you're dropping down from the stadium.

Normal Reward: Wonderful Figure No.065 Wonder-Astronaut

Hard Reward: Wonderful Figure No.063 Wonder-Death

101% Hard Reward: Wonderful Figure No.116 P-Star

Operation 009-B

Secret Mission 003 (Kahkoo-regah)

After completing Mission 002, the first Kahkoo-regah in the level will appear back at the starting position of the Mission area.

Normal Reward: Wonderful Figure No.100 Wonder-Antenna

Hard Reward: Wonderful Figure No.093 Wonder-Fixit

101% Hard Reward: Wonderful Figure No.118 Platinum Robo

Secret Mission 006 (Kahkoo-regah)

After dropping into GEATH-Wahksay, use the Wonder-Liner to trace the "D" shape on the ledge behind you: doing so will reveal the level's second Kahkoo-regah at the center of the platform (and a whopping one O-Part.)

Normal Reward: Wonderful Figure No.078 Wonder-Bulb

Hard Reward: Wonderful Figure No.068 Wonder-Vender

101% Hard Reward: Wonderful Figure No.106 Wonder-Captain

Operation 00A Epilogue

Secret Mission 006 (Kahkoo-regah)

Just like in the Prologue, after completing Mission 005 a Kahkoo-regah will appear inside the bus under you. To get inside, you must once again use Unite Hammer to break open the roof hatch at the front of the bus.

Normal Reward: Wonderful Figure No.117 Virgin Victory

Hard Reward: Wonderful Figure No.053 Wonder-Sister

101% Hard Reward: Wonderful Figure No.105 Wonder-Goggles

Operation 101

Operation 101 consists of 31 Secret Missions, all of which count for the Operation Annihilation Bottle-Cap.

Operation 101 is a challenge level unlocked by completing every single Kahkoo-regah on Normal, Hard, and 101% Hard (the same criteria as unlocking the GEATHJERK Slayer Bottle-Cap.) It's an enormous, multi-level Kahkoo-regah that must be completed in a single session, and features not only the return of some of the game's more difficult Kahkoo-regah challenges, but also entirely new challenges found only in Operation 101.
