Get the Dr. Hare's Secret Lab card from the store (It costs 250 credits). Visit it.

Walkthrough
You will be on a rocky hillside. Go up the hill, and go in the little door. Go right, land on the moving platform, and go to the top right. Talk to the guy, and he will tell you to get three colored key cards. Go to the middle right, and enter the big brown door.

The Key Cards
Go around until you find a gateway switch. Locate a crate near one of them, and push it onto the switch. Do this with all three switches. Find the doors with the cards. Get all of them, then go back to the brown door. Go back to the guy with the rabbot suit, and click on the suit. Your rewards will be 50 credits and the ability to costumize the rabbot suit.

Goofs
Glitch: If you visit the mini-island from Early Poptropica or Super Power Island, and you have put on the jetpack or flying power, you will be able to use it while completing the quest.This is helpful when a guard catches you. You can fly up to the door, exit, and enter again. You have all the cards that you earned.
