A talking coyote formed from parts of the celestial landscape, as in 'The Simpsons' (c.) episode about the Guatemalan Insanity Peppers. You have to watch the episode, I wont go into the whole thing.
Also a person who gives guidance and advice to those who have never tripped before. He helps them stay grounded and not hurt themselves or others.
"...an that talking coyote was just a talking dog..." (Homer)
"Hey, thanks Space Coyote, I thought I had really brained my damage"
"help me Space Coyote!"
