Bug eating is a very good one, I think.

Getting the stuff from pet stores is also a very good way to go about it. Bugs eat toxic stuff that can make us sick. The ones in pet stores have been eating normal stuff for a while, so you won't get an accidental blast of some dangerous plant poison in your gut or something.

Pet stores also have mealworms, which break into a milky white substance, in little tubs like small margarine tubs. This was one I suggested and I think it might already be on the challenge list. Usually they're fed to lizards, larger aquarium fish, and such. They're only as long as the last joint on your finger, but they're nice and fat and cream filled, just like a worm should be.
