Remember how I had all those coffee cans and was looking for uses for them, well, we still have a lot that haven't been "assigned" new roles.
So one rainy day the kids decided to play with Nute and hide treats under the cans.
One can had a special surprise--his Kong, which you can shove full of treats. This drives him crazy because he can't get them out easily.
They let him back in the house with the Kong and he worked on it quite a while. :) There's even a user's guide for the Kong, if you're curious.
