When you enter, you get a time-stamped ticket. You have to find four named monsters in the maze and punch your ticket with the uniquely-shaped hole puncher found at each monster. If you can find all of them and get out within 4 minutes, you can get a pre-recorded cheer from the kiosk at the exit (honor system because Germany).
Enjoy the pics.
