Boomons

In the Super Smash Bros. series, sometimes Pokemon balls can randomly appear. In the game you can grab them and summon a random Pokemon. In The Baby Boo Busters: Project Smashin', there will be a very similar feature, only the only difference is that you can summon Boomons from TMK's Boomon.

(Oof I know no Boomon nor what they do... I need some help oof.)
