Another in the Genius Bunny series. This one hangs from the inside of bunny's home with a bolt, washer, and wing-nut. There's three wooden slats that bunny has to move aside in order to get to the treat hidden in a recess behind the last slat. It is so much fun to watch them figure it out.
Make 'em work for it.
Use your imagination to stimulate theirs! Treats not included.
