Special Kit 3

From the Super Mario Wiki

Special Kit 3 is an unlockable in Mario vs. Donkey Kong 2: March of the Minis by doing all the Shy Guy Smash games. Instead of Mini Marios, Mini Donkey Kongs are used. The place has all the enemies and obstacles of the entire game. The place is based on Jungle Hijinks, but a higher pitched music and a different background. Like Special Kit 1 and Special Kit 2, they are only in Level Editor.
