A laugh-out-loud cautionary tale (for children and grown-ups) written by Catherine Emmett and illustrated by David Tazzyman, bestselling illustrator of the Mr Gum series and You Can't Take an Elephant on a Bus.

Digby David slammed the door,
and dumped his bag upon the floor.
"Daddy! I DEMAND a pet,
Why have I not got one yet?"

Digby David wants a pet, but not just any pet - it has to be TWICE as big as Reuben's guinea pig and even better than Lily Jean's cat. Digby David's Daddy does what he's told, and soon Digby has a guinea pig, which he loves with all his heart... for half a day. Digby demands bigger and better, Daddy's hair gets greyer and greyer, and when Digby's dog gets boring too, he insists Daddy buy him... a gorilla!

A hilarious tale with a 'be careful what you wish for' message, especially if you wish for a gorilla and don't look after it properly.
