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 all Jump attacks, solo Hammer attacks, and regular Chopper Bros. attacks. The Glurps can be defeated with other Hammer attacks, although their main 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.
