Hypnotic Seashell
An oval-shaped shell, which appears to be multi-colored and hypnotizing. The shells are actually a part of a special species of muscle on Nautil, whose flesh is extremely iridescent due to deep-sea conditions. In nature, these clams open up their mouth and let the glowing iridescence draw in any bottom-feeders before snapping closed. When one of these clams die, they leave behind their shell. Sometimes, you will be lucky enough to find one still shining as if it were alive.
