Teruteru

Teruteru are enemies found in Wario Land 3 from the Wario Land series. They are ghost-like creatures who attach to Wario's head and makes the screen dark, preventing the player from seeing. To get rid of this enemy, Wario has to hit a wall or a solid object. When floating, it can be defeated by a Smash Attack or a Ground Pound.

Trivia

 * Teruteru seems to be based on teru teru bōzu, a kind of handmade paper or cloth doll from Japan associated with the weather.
