The Skippy Gremlin

A mystical being that visits young stoners to show them the ways of the bong
His body shape changes depending on how much marijuana is in your system, and he can be heard by his iconic mating cry of "Are ye skippy?"
He is associated with many other ethereal beings such as the RA coon

"Lads I just hit that bong so fuckin hard, the Skippy gremlin will be visiting soon"

Or

Stoner 1:"Lads I just fuckin heard something"
Stoner 2: "Don't worry my fresh crossaint, it's just the oul skippy gremlin doing the rounds"
