Acro-Bandit

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."

however, if you kill this one whe he looks around before he pops up, it is easier and you only have to kill one.
