Query: Encourage a wild imagination (without batteries)

If you don't have any of these, they are indispensable. My house is covered with little animal groups who either socialize or eat one another. They nurture an already wild imagination with no batteries required. More realistic looking than other "tubes" or tubs that I've seen at big toy stores and made better (seams match up and they're painted correctly). Great buy.
