Birthdays and Dances is a fan story written by ArthurEngine.
Perry Register and Wendy Chandler share a birthday, and they are having two parties on the same day. Queen Grace, after hearing about the school dance, plans to kidnap Wendy, and she does just that. It's up to Katie to save her. But not without unexpected help from Perry's shapeshifting powers.
- Gus comes back to life in this story.
- The birthday half is very loosely based on the Arthur episode, Arthur's Birthday, where A.T. Read and Mary A. Crosswire share a birthday.
- This is the 2nd episode where Katie temporarily borrows Tommy's watch.
- Wendy's dad uses the word "Eh?", being a nod to the fact real Canadian people often say "eh?" at the end of questions.
- Perry tricking Grace into thinking he's going to kiss her, only to replace himself with Gus, is a reference to Mario Power Tennis, where Peach Mario tricks Bowser into thinking she's going to kiss him, only to replace herself with a red Birdo.
- The song Melanie sings is based on Mimi's song from Digimon: Digital Monsters.
- The second verse in Krystal's song is based on the Donkey Kong minigame music from Mario Party Six.
