The Caustic Dweevil is a member of the Dweevil family, a non-aggressive enemy found in Pikmin 2 that attacks in self-defense. As it's typical of Dweevils, it picks up any treasure or enemy body it can find, only releasing it when Pikmin attack. The only offensive measure the beast can take is spraying an acidic bodily fluid on enemies, which drowns all Pikmin types except blue ones, making them the best choice in battle against it.
Throw Pikmin on their small heads. Although they can harm non-Blue Pikmin, they are weak and often die before getting a chance to attack at all, and this does not kill Pikmin instantly, allowing them to be whistled to safety by a captain if they do come into contact with it. Purple Pikmin are particularly useful in defeating large numbers of smaller Dweevils with ease, since they stun when thrown, halting any enemy attacks, usually until death.
Run up to it and punch it until it begins its attacking animation, leaving plenty of time to run away before it attacks. Run back and continue the assault when the acid stops.
