In this case maybe the issue is not about the bunny. Perhaps she doesn't want to go to school and she is focusing in the bunny thing to create a conflict.
It happens with our kid too. He is about the same age and he has trouble with transitions. When there is something that he doesn't want to do, then he creates scenarios that lead to conflicts. Like asking for a toy he knows he lost, or something that he doesn't have, etc..
What help us is to learn what's really the issue and try to address that instead of the conflict.
Isn't that a custom license plate?
