Celebrity chef Mrs McWhiskit returns to Sunnysands with plans to make the town out of cake. The great Cake Bake is happening at Miss Smiley's cafe, and it's not long before Mrs McWhiskit is bossing everyone about. Miss Smiley asks her accident-prone husband Mr Whoops to help Mrs McWhiskit. When Grandpa learns of this, he puts his Shrinking Cap on so that he can go to the cafe and help out.

As expected, Mr Whoops starts having little accidents. Grandpa tries to stop things going wrong but ends up in the cake mix by mistake. Luckily, Josh is there to create a diversion so that Grandpa can escape. Then he has a brilliant idea for keeping Mr Whoops occupied so that Mrs McWhiskit can get on with her job - by making Sunnysands figures out of icing.

At last the cake is done, but Grandpa has one more job to do. He pretends to be a model of himself and tells Mrs McWhiskit to stop being so horrid and bossy. Show less
