Geemer

Geemers are the Goombas of Metroid. They have spikes, and climb on walls with their six jointed legs.

Biology
Geemers have a diet of human refuse and seem to be larger, extraterrestrial relatives of the terran Dung Beetle. They also share traits similar to those of a Porcupine. They come in a variety of colors, ranging from the usual purple, to the Norfair-exclusive silver variant, and the rare orange Geemer.

Trivia

 * Geemers are edible if you remove the spikes.
