Imagination!

Do you know what has one rubber foot for jumping on, and a special machine on top for throwing pies, in case they want to have a pie fight?

I wouldn't have been able to guess either. It turned out to be one of Daisy's pacifiers that Rory was playing with this morning. I don't know where he got the idea for pie fighting, lol. But he was bouncing the paci on it's nipple, and using the ring part to throw imaginary pies, complete with sound effects.
