a walliwallibus is a furry 3-eyed 3-nutted mammal with 5 legs, the 5th actually being a disproprtionately large penis that can instill orgasm upon being looked at.
walliwalbus... I actually dig the name, but think it sounds like a mammal that has yet to be discovered...
too early for the imagination to wander and figure out what it would look like, he's okay in my book.
