Monster Max and the Bobble Hat of Forgetting

Max is just an ordinary, slightly scruffy boy, until he burps, when he turns into a huge monster, with teeth like swords, who can jump over buildings, roar and eat whole dustbins. It''s great being a monster whose aim is to ''protect and do good stuff'' until Max sneezes, when he turns back into a boy again, sometimes far from home and dressed only in his pants.But something starts causing a lot of damage in his quiet suburb and it isn''t Max. Trailed by his nemesis, Peregrine, a boy his age who has invented a POOP (portable operating omni prison) machine to catch the monster, Max has to find the real culprit before Peregrine catches him...
