Thwarted

I came home from the Rescue tonight, all excited to see how Kiwi and Sigmund did with their new foraging toys.  Sigmund hadn't touched his.  Here is what I found in Kiwi's cage:

Instead of twisting the face of the toy until she could reach each of the treats, she removed the screw so the face dropped off and she could reach all of them at once.

I was able to put it back together, and refilled the thing.  When I put her back in her room and came upstairs, she was dutifully manipulating the appropriate pieces.  I am counting the minutes until I hear the crash.
