Leprechauns

The leprechauns are fairies who store away all their coins in a hidden pot of gold at the end of the rainbow. Bender of universe 1 has stolen a pot of gold from the leprechaun universe and Bender of universe Γ has called Nibbler a leprechaun, stepped on a leprechaun  and been chased by three leprechauns on surfboards together with Morris and Fry, presumably, after stealing a pot of gold from them.
