In the enchanting underwater kingdom of Coralia, the mermaid-animals called FurFins are getting ready for a sleepover! But will everything go as planned?

Deep beneath the silvery waves, in a kaleidoscope of colorful coral, lies the magical kingdom of Coralia. This is where the FurFins live, and today is a very special day: StarTail has invited her friends to a sleepover!

StarTail is nervous--what if it doesn't go well? But soon RubyTail is helping put up a cozy tent for them to sleep in, TinyTail is making friendship bracelets, and they all help CherryTail to bake her famous cupcakes for a midnight feast. That's what friends are for! But when they hear a scary noise outside the tent during the night, will everything be ruined? Or will it be the best sleepover ever?

With a sparkly cover and adorable, pastel illustrations, this charming underwater adventure continues the exciting picture book series featuring the endearing FurFins with their glittery tails and adorably furry faces.
