Judging by the Tokyo Metropolitan Government Building featured in Showdown With Omegaton, it's assumed that the level's location takes place in the center of Shinjuku City.

Despite having an idle animation in-game, Nimbus' talking animation is used for both an idle animation and a talking animation. His actual idle animation is partially unused since its only used properly in the final level, Showdown With Omegaton.

The Wii version features two unused bonus cutscenes for the level Chicken Con Carnage. The first cutscene revolves around a news reporter by the name of Chuck Gavel reporting the strange animal behavior caused by the Fire Flyers possessing them. The second cutscene introduces a removed character named Wind Boy.

The game has a game-breaking glitch that triggers a blue screen of death. This glitch occurs whenever a Fatal Lua Runtime error occurs and can be caused in specific scenarios, with two known examples being when two different dialogue pop-ups try to appear at once, and if you grab 100 Fire Flyers at once during the final zone of Chicken Con Carnage.

Pressing the C button/right bumper/R2 button will automatically target the camera, but what it targets differs depending on what mode you play. In the single-player campaign, the camera is targeted directly towards the L.O.A.D. STARR objective; it is unlocked upon successfully grabbing all 50 Fire Flyers within the current zone, and will remain unlocked until you advance to the next zone. In multiplayer, this mechanic works differently by instead targeting the other player. Although this mechanic is present in all three versions of the game, the Wii version is different in that it can only be used in multiplayer, unlike the PlayStation 3 and Xbox 360 versions where it can be used in both single-player and multiplayer.

Although the Wii port of the game was primarily developed with the Wii Remote and Nunchuk combo in mind, the game has limited Classic Controller support via the left and right analog stick.
