Peter loves peas and they turn him green and, also, rather smelly... Rejected by his classmates, Peter is worshipped by some nice, green, aliens and whisked off to their planet to become King. However, there are no peas there and Peter becomes a nice, pink colour again and stops smelling, so they send him back to Earth. This is a pleasant enough tale. My son found it funny, but my 3 year old daughter was definitely not amused (she didn't like Dirty Bertie either), so it depends on what they find humourous. If you have a little boy who likes toilet humour then this will probably be a winner.
