Deema's Magic Supplies Store is the shop segment from the episode: Bubble-Cadabra!
Goby wants to do a magic trick, so he goes to the magic store, run by Deema. She tells him he will need a top hat and she asks if he'll want a bunny filled hat, or one without; he chooses a hat with a bunny. So she uses her magic to make one appear! She greets Bunbun, then sees a whole bunch of bunnies pop out and run off. Deema needs one bunny in each hat so they ask the audience to help them capture the bunnies and put them back into their hats. At the end, Deema manages to give Goby his hat, with only one bunny.
