A Triclops.

Triclops Terror is a minigame in Metroid Prime Pinball. It is made up of three levels, as with all minigames in Metroid Prime Pinball. The objective is to destroy all of the Triclops by either using bombs or by simply launching Samus at them. The Triclops can only attack in one way, by picking up the ball and throwing it between the two flippers at the bottom of the screen, making it a one-hit kill. Destroying all earns Samus an Artifact or a Special.
