Funnybones. The Pet Shop

"All he does is dig holes - and bark!" "Woof!" Barks the dog. When The Big Skeleton and The Little Skeleton become fed up with The Dog Skeleton they decide to swap him at the pet shop! They start off with a goldfish but soon get tired of him and swap him for a parrot - but soon they get bored of him too . . . Eventually the pet shop owner gives them a box to take home with a surprise pet inside. What do you think it will be?
