Yup, Ricky Gervais wrote a kids book
Cowardly wobbler that spends its days avoiding the Grundit. The Puddloflaj looks like a fat useless blob. It actually doesn't have an ounce of fat on it -- it's water retention. In fact it's nearly 100% water, sort of like filling a balloon from a tap. Baby Puddloflaj can be used as water bombs.
See? Told you. The book takes on a real surreal quality if you imagine Gervais' character David Brent of The Office reading it.
