Batteries?

Lennox and fam went to the Chicago Contemporary Art Museum last weekend and one of the activity centers allowed kids to make sculptures. Lennox wanted a blue elephant so he helped construct the amazing work pictured to the left (note mama's addition of the critical peanut located at the end of the trunk). That night, he wanted to sleep with the blue elephant. Needless to say, in the morning, the sculpture had come unglued into many small pieces. Lennox insisted papa should "fix it." After chatting for a bit, Papa asked Lennox what was needed to fix it. Lennox's reply was a pause and then simply, "Ummm, ..... batteries!" Obviously.
