Stumper

Stumpers are enemies in Captain Toad: Treasure Tracker. They are brown stump-like enemies with a wooden spike on three sides and a smiling face on the front. Stumpers are always seen appearing in stacks and sometimes even adjacent to each other, moving as a large rectangular prism. They are immune to all attacks. Captain Toad and Toadette take damage from only the sides of this enemy. Traversing across Stumpers is a recurring theme in levels that they appear in.
