What better way to celebrate the milestone of 20 books in a series than to write a story about a birthday, Greg Heffley's birthday.
Greg's sure his family is planning a surprise party for him. Unfortunately, although he's excited about it, he's also a bit nervous, too.
What could go wrong? Well, his family forgetting his birthday is what.
How can that happen? Well Greg soon finds out what led to it, then in true Heffley style his family decides to make it up to him and plan a super dooper party.
That means decisions for Greg, or so he'd like to think.
Like whether to have a family party at a restaurant, or friend party somewhere like the trampoline park or an escape room or the museum.
Or perhaps a family and friends and neighbours party would be even better.
Greg gets stuck in helping to organise his own party, sharing ideas for invitations, gifts, and entertainment. Mum's got slightly different ideas though. Will Greg's party be all he dreams of? Could anything else go wrong?
Written in diary-style, with Greg telling his story in the first person, Partypooper is packed with Jeff Kinney's recognisable black and white illustrations.
Check out the official Diary of a Wimpy Kid website for a bunch of downloadable writing and drawing sheets, puzzles and games, and an activity kit and teacher guides.
