Careful, you'll lose an eye.
This page or section needs more images.
There's a whole lotta words here, but not enough pictures. Please fix this.
To do:
  • Document the demo version of the game
  • More unused graphics such as unused pieces for a scrapped minigame, world splash screens, and unused food graphics such as grapes.
  • Prerelease screenshots such as a screenshot in a Japanese magazine which shows an underwater level that's identical to stage 10 of Green Grounds but with a different background. Source

Kirby Mass Attack can best be described as Kirby meets Lemmings. Kirby gets split up into 10 smaller (and somehow more adorable) Kirbys that have to work together to destroy enemies, open paths, and get food. It is also the successor of Kirby: Canvas Curse in some ways, and contains unlockable subgames in a variety of genres (including a vertical shoot-'em-up and what's pretty much a remake of Kirby's Pinball Land).

Unused Graphics

To do:
There's more sprites to add and other graphics, including graphics intended for remakes of the minigames from Kirby's Adventure; you can find them here.

Unused Palette Swap Feature


It seems you could originally modify Kirby's color, like in Kirby Squeak Squad, but this feature was scrapped fairly early. The graphics for the menu can still be found in the game, though they were never translated from the original Japanese. Available colors would be indigo, cyan, grey, light pink, pink, red, orange, yellow, blue-green, green, purple, dark grey, and beige.

Unused Enemies

UFO Shuffler Hammer Knight Block Dragon

UFO, Shuffler, Hammer Knight, and Block Dragon have unfinished shading.


Only Toroppon's cart is fully detailed.

igloo-shaped Pytago triangular Pytago trapezoidal Pytago

Only the igloo-shaped Pytago sprites are complete. All three have red guidelines on each side.

Spiky Rocketon Carryon Giga Clanksprout Tortletummy

Spiky, Rocketon, Carryon, Giga Clanksprout and Tortletummy all seem to be finished.


Unused Subgame Elements

There are even some unused elements in the subgames, particularly Strato Patrol EOS, which was to have Plasma Wisp as an enemy and King Dedede as a playable character.

Unused Hint


An unused screen, in Japanese, with a hint about grabbing:

Can't grab on...

While hanging on to a star,
you cannot grab on to other things.

In the game Kirbys can grab things even if they are hanging on to the star, but this hint indicates that might not have always been the case.

Unused Music

To do:
Find audio tracks and upload them here

A track that sounds like it might have fit into Strato Patrol EOS.

A seemingly celebratory theme, using part of the main theme motif.

Regional Differences

To do:
upload more of the Japanese enemy credits. source for upper screen. source for lower screen.

Removed Enemy Credits

The Japanese version has an enemy credits sequence with 35 pictures and Kirby having a picnic that was, for whatever reason, dummied out from all subsequent versions. The untranslated graphics are still in the game files. It's worth noting that the sprites used to represent the enemies Stickle and Ill Gate in the enemy credits are not the sprites used in the final version of the game but are actually unused sprites.

Graphical Changes

Japan US
Known as "Nightmare Enterprises" to Americans. They took a page from 4Kids and removed English text.

The US version of the Strato Patrol EOS minigame's game over screen, instead of localizing "Holy NightMare" to "NightMare Enterprises", simply removes the text entirely and replaces it with a background featuring purple clouds in the likeness of Nightmare himself (or eNeMeE, as he is known in the English dub of Kirby: Right Back at Ya!).

Development Text

The following pieces of development text can be found in the ARM9 binary.


The "map" folder in the game's filesystem contains the levels.

Internal Project Name

The project's internal name is "wadogo", according to the above development text and the filename of the SDAT file, "WADO_SND_new.sdat". The name also appears in the filenames of some press materials released by Nintendo.


Please elaborate.
Having more detail is always a good thing.
Specifically: How does the game detect that it's a copy?

After loading the game, it will freeze with a blank screen if it detects that it is a copy.
