Tail Thwomp

A Tail Thwomp is a Thwomp with a Tanooki tail that appears as an enemy in Super Mario 3D Land. They act very similar to Grindels.

Super Mario 3D Land
In Super Mario 3D Land, Tail Thwomps (unlike the regular stationary Thwomps) can jump about in a wide set area; because of this, Mario has to pay close attention to their movement patterns in order to avoid being flattened. When they float about, its reminiscent of the way Tanooki Mario floats, they even make the same noise while doing so. Unlike normal Thwomps, They only have a face on one side, due to the tail on their back. Tail Thwomps can be defeated by transforming into Statue Mario and either landing on them or having them land on him, like normal Thwomps. Only two appear in the entire game, and they both appear in World 5-1.

Trivia

 * In Mario & Luigi: Partners in Time, one of the Tanoomba and Tashrooba's attacks involves turning into a Thwomp with a Tanooki tail in midair and slamming to the ground.
