Rabbit = bullet right? Hmm, i've always called mine a little bullet. I spent $20-30 cdn for the first two, pieces of crap though, they broke too soon
My current toy i use is a smaller bullet, and it was $45 cdn, and i love it, i can fit it on my keychain and no one knows what it is!
Make sure you avoid using stronger batteries like energizer or duracel because they are harder on the motor. Use the dollar store batteries, and you'll get more use from your toy.
