Zippy's cousin Zippo rings him up asking if he can come over, but Zippy's too scared to ask Geoffrey, so he tries to make sure they don't find out. Zippo keeps making mess, but poor Zippy keeps getting blamed for it and everyone gets confused. Rod, Jane and Freddy sing "Zippy's Up To Something". Geoffrey reads a story called 'Shhh! Don't Tell Monkey'. Then he finds out Zippo's come to stay and understands why everyone got confused before.
