The LSD Snake is a giant snake created from D. L. Diamond's "space dust". The snake only appeared in "Don't Be A Negaton."
The snake spawned from an LSD Unicorn's head. It originally was the horn, but suddenly transformed into a snake. The snake then swallows Jared, who falls in a colorful swirly portal. The snake was most likely blasted by The Galactoids or just disappeared when the convicts woke from the hallucinations.
