Acro-Bandit

Acro-Bandits are enemies in The Minish Cap. They are commonly found in the Eastern Hills. Before the group comes out from underground, one pops up to see if the coast is clear. He then calls the other Acro-Bandits and they stack up one on top of another. The Acro-Bandits then go after Link. However, the whole group coming out can be avoided by defeating the one that looks around. Be sure to defeat them if they fall down, because after a few seconds, they will dig back down into the ground to prepare for another attack.

Quote from The Legend of Zelda: The Minish Cap Acro-Bandits figurine:

"Appears in the Eastern Hills, ect. Five of them pop out at once. If you smack each one as they pop out of the ground, they’re a piece of cake."
