You stop and try to think. How did you become a rabbit? The other rabbit bit you!
Was it a wererabbit? Is there such a thing as a wererabbit?
The only thing you can think to do is go back to the rabbithole and comfront the bunny. Rabbits, unlike wolves are vegetarians so you think you'll be safe.
You hop back to the rabbithole. You're just about to enter when you notice that even by your new size the hole looks small. You're large and a bit plump, and you're not sure you'll be able to fit.
