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, solo Hammer, 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. The bite attack may be similar to the Sworm's, the only difference is a Glurp will move in a counter-clockwise when biting. When damaged, a Glurp may split into two Glurps, but they will both have the same total HP.

Trivia

 * Glurps have a passing resemblance to Creepers.
