Mud Troopers are enemies in Captain Toad: Treasure Tracker. They are zombie-like enemies, with yellow eyes, blue hair, red shoes, and tan bodies. When they see Captain Toad or Toadette, they will chase after them; to complicate matters, the Mud Troopers often appear in groups, making stomping them a potentially unwise tactic.
They can be defeated by landing on them, throwing a Turnip at them, or using a Super Pickaxe. Another potentially risky method involves usings Chargin' Chucks, which can be lured into plowing through several Mud Troopers. Flaptors can also defeat Mud Troopers when they attack, however, this can only be done in certain levels. Also, staring at one long enough with a head lamp can temporarily disable them, however they will soon rematerialize.
