Stumpets are not mobile, but they have very powerful explosive attacks so it's wise to keep your distance from them. Sometimes defeating a Stumpet is the only way to get further into Barrel Volcano.

Attack Pattern: On the map they stay in one place, and erupt occassionally, creating Magmuses. In battle, they take one turn for "getting furious!" and on the next turn they use one of their attacks. Va Va Voom will cause high damage to one character, and Backfire causes medium to high damage for one character. Usually you will fight one Stumpet and a bunch of Magmi.
Basic Fighting Strategies: It can take a lot of hits, but it also causes a lot of damage, so you may want to take Stumpet out first, so it doesn't get to attack on it's second turn.
Advanced Strategies: One possibility is to use Snowy or Ultra Jump to take out the Magmi and damage Stumpet all at once. This is a pretty good strategy for reducing the amount of damage your party takes. Stumpet's attacks can't be blocked.
