Koopa Kid in Mario Party 6
|First Game||Mario Party|
Mario Party 2
Koopa Kid (called Baby Bowser) takes the place of the star once a player has taken it. If you land on his space he takes five coins. If a character wins a Bowser Bomb, the item will activate on its own and turns Baby Bowser into Bowser.
Mario Party 3
In this game, Koopa Kid now owns an Item Shop in the same location as the one owned by Toad on the board, with each turn randomizing whose shop will come up as a player passes. Koopa Kid's items are all the opposite of ones sold in Toad's store (Example: Toad sells Boo Repellent while Koopa Kid sells Boo Bells), except for the Item Bag and the Skeleton Key. Koopa Kid also appears in several of the Mini-Games, serving as the "losing prize" in the Item Mini-Games.
