Sworm

Sworms are black worms found outside Beanbean Castle Town in the game Mario & Luigi: Superstar Saga. They have two methods of attack – burrowing into the ground and popping back out beneath Mario or Luigi, or burrowing underground, popping up in front of one of the Bros. and biting him. The former method can be countered by jumps, and the latter by Hammers.

Trivia

 * In Mario & Luigi RPG 3, Fawful-resembling Sworms are the only enemies to bear a resemblance to Fawful who are neither a new specie, or a specie introduced prior to Mario & Luigi: Superstar Saga. (such as Fawful-resembling Shy Guys, Magikoopas, etc., all of which were introduced before the creation of the Mario & Luigi series.)
