The Koopa Kids are minions of Bowser who have only appeared in the Mario Party series. They are known as Mini-Bowsers in PAL territories, Mini Koopa in Japan (Bowser’s name in Japan is Koopa) and Baby Bowsers in Mario Party, Mario Party 2 and Mario Party 3 (not to be confused with Baby Bowser). The Koopa Kids resemble miniature versions of Bowser (and are therefore very similar in appearance to Bowser Jr. and Baby Bowser). Originally, the Koopa Kids were nothing more than minions indirectly fought by the Mario crew when the Koopas attempted to crash their parties, but in Mario Party 5 one was finally made playable (despite this, Bowser shows them no mercy when they land on his space).
Koopa Kid is the eleventh character in the Mario Party Series. His primary color is orange. Mario Party 5 also introduced Green K. Kid, Red K. Kid and Blue K. Kid who, as their names imply, are colored differently. The aforementioned colored kids are one Koopa Kid split into three. It is unknown if other Koopa Kids are capable of duplicating like this also. In Mario Party 7, Koopa Kid is no longer playable. He has his own Orb that Bowser sometimes sells in his shops. When it’s used it will add a Koopa Kid Space to the board.
Koopa Kid’s future is uncertain, as he did not appear in Mario Party 8 or Mario Party DS. Additionally, Bowser Jr. made his Mario Party debut in Mario Party DS, implying that Koopa Kid may have been retired in favor of him, although this is unconfirmed.

It is unknown how many Koopa Kids there are. Originally, there seemed to be only a few, but Mario Party Advance seemed to imply that there are close to hundreds of them.
