I know a cool trick to bring the rabbit into other rooms! It's kinda hard but worth it. Get 20 or 50 stars to make the rabbit appear. Then, go catch the rabbit, but don't take his star. Instead, pick him up, take him near the door you want to take him through, and set him down in front of it. then, go through the door, and immediately turn around and press A and B and toward the door at the same time. This could take some practice, but you should get stuck in between the door. Pick the bunny up. turn around, and set him on the other side of the door.get out of the door and do whatever you want with him!
