Makha-na

When the genie caught a cold due to being splashed with guava juice, his magic went out of control. The only way to cure him was with the fabled Orb of Makha-na. To get it, Aladdin travelled to a cave, where he was confronted by Makha-na. Seemingly a huge, powerful shape-shifter, he put Aladdin to three tests. These obstacles he had to pass were riddles. When Aladdin passed, Makha-na revealed himself to be a tiny insect using gigantic mechanical suits to frighten away the unworthy, and presented Aladdin (who was worthy) with the Orb. The genie was cured, and the day was saved.

Makha-na's voice is that of Dave Thomas, I think. That would be the "Doug McKenzie" Dave, not the "founder of Wendy's" Dave.
