Spike (Yoshi's Story)

Spikes are metallic creatures appearing in Yoshi's Story. They are sentries of sorts, each one jumping back and forth in one small area of ground and guarding it, or merely standing in one place and periodically leaping straight up. Spikes make the sound of a camera shutter every time they jump and land. They seem to be made of a bronze-colored metal (making tiny sounds as they jump), have large sharp cone-shaped protrusions that form the tops of their heads, and are indestructible. They are found only in the levels Bone Dragon Pit and Magma Castle.
