It is Mummy Pig's birthday. Peppa, George and Daddy Pig are just as excited as Mummy. They have lots of fun preparing secret, birthday surprises for her. When Mummy Pig sees her beautiful cake and opens her present she is absolutely delighted.

The family's car breaks down and it has to go to the garage. While it's being fixed, they borrow a new one with lots of exciting buttons. One makes the roof go down, one makes the windows go up and one squirts Daddy in the face!
