Ernie is a genie that appears in the Season 9 episode "The Clumsy Genie". He is first seen when he is asked to cure a cold of a prince. But after given three chances he fails and as punishment he is tossed out the window to the "Nut Cracker" (an elephant hypnotized by a snake charmer's music), where his lamp is crushed and he is squeezed out and flung into a wall.
He is revealed to be good friends with Tebuli, another genie.
