You must have with you a character who uses magic as a skill, if you don't have anyone go ahead in the game and you will have the right bunny for that job.
if you are referring to AFTER the ghost chases you out of the house initially:
hint: the bunny is purple and a mythical creature.
if not, the storyline is fairly straight forward and "leads by the nose". If it is open to you, you should be able to access it with what you currently have available.
