Pokey

Pokey is an enemy that appears in the Gameboy Zelda games. He is one of the enemies appearing in that game that was transplanted from the Mario series.

Pokey is a cactus made of four individual segments. The topmost segment has a face. Each time Link strikes Pokey with his sword, one of the segments is knocked loose from Pokey's body. It ricochets around the screen briefly before destructing.
