In the The Mad Doctor's Attic, when Mickey thins out the walls on corners, various unknown costumes appear and look as if they could fit Big Bad Pete, or a large sized-character. The costumes are actually Pete's old outfits from various cartoons.
- It is advised to NOT wear the Brave Little Tailor Costume while working on Scrap Metal-related task such as fixing broken buildings, as the costume converts salvaged metal into cloth.
- The Wizard Hat is the first costume piece you get.
- Mickey's ears are realigned while wearing Brave Little Tailor, Construction, and Sorcerer costume. For the Football and Firefighter costume, the ears poke through the headgear.
- All of Mickey's costumes are based off his original cartoons while Oswald's are based off of other Disney Literature and one of his own cartoons (Oh What a Knight).
- The costumes are helpful depending on which one you're wearing like for example, if you need lots of scrap metal, the construction outfit is the right match.
- If you've bought a costume piece before finding it in a chest, you will get some pins instead.
- The Sorcerer's Apprentice Costume is unavailable on the Wii version of the game. Instead, there is a special feature after the game has been beaten.
