Hey! Them's Leachies. That's an animal that lives near nuclear waste leaching beds like those that were (and maybe are) still out at the National Lab.
What happens is that the animal, jackrabbit or coyote, gets crapped up, their hair falls out and they turn purple.
Yep, them was Leachies. Had 'em right cheer in Ideeho back in the 60s.
Giat......Giat......Giat........stick poke goes here.
