Peppa and Rebecca Rabbit would love to be mermaids! When they come up with a plan to have an under-the-sea party, Peppa gets carried away and invites all her friends over for a swimming disco with starfish-shaped sandwiches and a real beach! There's just one problem... Mummy and Daddy Pig aren't prepared for this at all . . . Can Miss Rabbit, Emergency Party Planner and Entertainer Extraordinaire, come to the rescue? Of course she can! Peppa the Mermaid has a super-sparkly holofoil cover covered with mermaid scales- it's the perfect present for every little reader and mermaid fan!
