How do you get rabbot ears in poptropica?

When you have freed the drones in the processing room, go right and you will find a door. (It says Bunny Drones Only.) When you try to enter, you fall through a trap door into the Preparing Room. Dodge the pistons and the squirts of goo and get to the right side. Up above, you will find rabbot ears and the way out.

When you put on the ears, you can pass through the door, and fool Dr. Hare.
