There are two genie ghosts in Dizzywood.

The green one is located in the Tanglevine Jungle and is named Onca (his name is inferred from the scientific name for jaguar Panthera Onca). He will give you Ghost Ray if you win once on Combo Drop.

The other genie ghost is located in The Explorer's Camp. He is named Yagu and is blue and guards the door to the Jaguar Temple. He will throw anybody out unless they have invisibility (and use it of course).
