Silico

Silico is a silicon-based life-form made by Telekineticlops when he was bored. It has the shape of a slug, though without stalks for its eyes, and has three breathing holes on each side of its stomach. Silico photosynthesis (so Telekineticlops doesn’t have to remember to feed it), metabolizing Si6H12O6 instead of glucose and leaving a shiny trail of crystals in its path. It can breathe underwater by breaking down water into hydrogen and oxygen, storing the hydrogen for release through a hole in its tongue (which it can spark with its phosphorous-lined teeth, allowing Silico to breathe fire). Despite this, Silico has no real practical use at all for Telekineticlops, and is really just an impressive pet and proof of concept for silicon-based life.
