And out of the the bush steps... none other than an enormous, compared to you, shopkeeper. As Mr Marlin steps out from the bush he laughs, " Ha, another one has fallen into my brilliant-bunny-berry trap!"
As he takes another step towards you he brushes past the berry tree, knocking it over. Underneath the roots are dipped in what appears to some sort of jar filled with purple liquid.
"Oops," titters Mr Marlin,"now you know how I make my pets, I really can't let you go."
This doesn't really matter to you as you still can't move and won't be going far, but if he keeps talking, he might reveal some good information...
"Anyway," Mr Marlin chirps,"those berries only have a temporary effect, in 2 hours you'll change back."
This is very good news as you never wanted to be a rabbit.
"So, to keep you a rabbit, I have to give you a booster injection." he smiled, revealing s syringe with a long needle attached.
Not so good news, but you are regaining some control over your limbs, you could try to run...
