See, the thing is, new babies are empty-headed. Total smushfaces, nothing in their brains, and they can't do anything. So, how come Barry's baby sister can draw pyramids? This baby is draining all the knowledge out of Barry's brain – wom, wom, WOM – and his mum's and dad's too. If Barry can't find a way to stop her, she is going to suck out all the stuff in everyone's head and all theirbrains are going to turn to mush. Aaaaaaagh!
