Toy Box

This boy will play with just about anything.  I think I'm putting a moratorium on buying any more toys for him until he enjoys them more than Tupperware.  He will play with them, don't get me wrong.  He just plays with Tupperware and/or a pail for longer than any other toy.  Here are a few pics of him being intrigued with his toys in his toy box.  (Please ignore the fact that his toy box is not a box.)

Which toy am I looking for?

It HAS to be the one all the way in the back of the toy box

After climbing into the toy box, he got tangled up by the toy box.
