Stumpet

Stumpet is an exceptionally rare and powerful enemy found in Barrel Volcano in Super Mario RPG: Legend of the Seven Stars. Stumpets seem to be formed from cooled magma which is shaped into a miniature volcano (which also resembles tree trunk, which is probably what it's name is derived from). Stumpets are apparently incapable of moving, despite this drawback they are still a force reckened with as their "Va Va Voom" and "Backfire" attacks are almost uneven in feriousity, luckily the attacks most be charged up ("getting furious!") so they are defenceless for a time.

Interestingly Stumpets are capable of spewing Magmususes, enemies with high defence. This may mean that Magmuses are created by Stumpets or atleast live in them, possibly meaning the two species may have symbiotic relationship.
