Glurp

A Glurp is a blue gelatinous enemy encountered by Mario and Luigi in Mario & Luigi: Superstar Saga. Glurps reside only in Joke's End and are extremely resistant to Jump and Hammer attacks. The Glurps' only weaknesses are the Firebrand and Thunderhand attacks.

In battle, a Glurp can attack by charging up and spewing out a poisonous pink cloud which can poison the Mario Bros. It can also bite its target, lowering the brother's defense. When damaged, a Glurp may split into two Glurps, but they will both have the same HP.

Trivia

 * It has a passing resemblance to a Creeper.
