Peter Pettigrew (aka Wormtail, Fatso the clown or Scabhead whe he was a rat) is a fat, ugly coward. Whe he first came to Hogfarts, he fell in love with James Potter and Sirius Black and followed them all around the school. Then, when he left school he ate too much baked beans blasted a street apart thanx to his huge behind. He farted so much gas out of him, that Peter turned into a rat.
