Connections to previous events
- Disney Press published a book adaptation called The Royal Slumber Party on June 4, 2013. Major differences include Clover helping with Jade and Ruby's dresses, and Baileywick being referred to as Clover, Mia, and Robin's friend.
- This is the first episode not to have Craig Gerber as a writer, although he is still story editor.
- Diamond White replaces Fiona Bishop (from Once Upon a Princess) as the voice of Ruby.
- Although Baileywick was quick to get rid of Mia and Robin in Once Upon a Princess, this time he is glad to be helped by them, which is presumably why the book refers to Baileywick as their "friend."
Cedric: Oh, I can't believe this. Fifteen years of sorcerer training, so a can be a warm-up act for milk and cookies!
Roland: Welcome to the royal sleepover
Jade: Ooh, come on, Ruby! Last one in goes to the dungeon!
Jade: Unicorns are my favorite animal in the whole world! (to Lulu) No offense.
Amber: This was my third favorite gown.
Clio: Amber, it was just an accident.
Jade: Sofia, I'm sorry we talk too much and laugh too loud for your fancy new friends. But we like to talk and we like to laugh.
Jade: And if that's not okay with you now that you're a princess, then maybe we shouldn't be friends anymore!
Sofia: Ruby! Jade! Wait! Please don't leave!
Jade: Hmm! I thought we were embarrassing you.
Sofia: You're not embarrassing me. You're perfect just like you are. You're sweet and loyal, and so much fun to be around with.
Clio: You know, Sofia's friends were kinda fun.
