1x103 - Bananas in Pyjamas

Rat has a lot of tennis balls that he can't sell, so he offers anybody who buys one the chance to win a trip to an amusement park called 'Fun World'. The winners are the Bananas, but B1 and B2 are in for a big disappointment. Fun World is just a few ricketty old rides in Rat's backyard. Rat has tricked them again, but perhaps there's a way to trick him back.
