A Gilles is a dark leprochaun and is born with a secret goal, to start a pixie farm. Gilles can often be found hiding in the closets of 10 year old boys, eating the heads off their action figures. If you see a Gilles, pull it's hair. It will snort yellow jelly beans.
"Why are the heads missing off my action figures?" "It must've been a Gilles..."
"I want some yellow jelly beans." "Then go find Gilles!"
