Gu Goomba

Gu Goombas are creatures found in the game Super Mario RPG: Legend of the Seven Stars. Mario and his party first meet this variation of Goomba in Bowser's Keep. Gu Goombas are just like regular Goombas, except they are much stronger, and green in color. Interesting enough, if Bowser is fighting alongside Mario, Gu Goombas will not attack and instead flee. However, if Bowser is not in the party, the Goombas will become confused, and sometimes attack themselves or other monsters. It is possible that Gu Goombas are an earlier form of Hyper Goombas.
