The new pet would be a dog, like a bulldog or something(just some dog with lots of fleas),then the interesting part is when the person with dog is waved at the waver gets a few fleas, the fleas just fly around there head and the flea pet Only last for a day.
2nd idea: we could have a huge fly and when you wave at fly you get a larva that lasts two days before it disappears.
