Shrooblet

A Shrooblet is a small, purple, Goomba-like Shroob with green spots, that can be found near Hollijolli Village during the Shroob invasion of the Mushroom Kingdom, as depicted in the game Mario & Luigi: Partners in Time. They attack by spinning into Mario or Luigi; an attack that can be easily countered with a simple jump. If a Shrooblet lifts its right foot before attacking, it will twirl into Mario; if a Shrooblet lifts its left foot before attacking, it will spin into Luigi. Shrooblets are among the weakest creatures in the Shroob military.

Trivia

 * Shrooblets resemble Octoombas from Super Mario Galaxy and Super Mario Galaxy 2.
