Bilibo for Christmas, and at first he didn't take to it like I hoped he would. But over time he has become more and more interested and has used it as a book container, a bath for his toys, puts it on his back and pretends to be a turtle, but usually he sits in it and spins himself around. We recently bought another one for friends to play with when they come over. It was becoming an issue. I've heard the Bilibo called "the cardboard box of the 21st century" and at first I was skeptical. Cardboard boxes are pretty rad. But we do love the Bilibo! It's awesome for Elliott's imagination and I love that it doubles as a toy and as toy storage!
