The fairy princesses' friends are having a party in Glitter Ocean.
They're so excited and set off in a pearl-encrusted shell boat,
wearing full-length mermaid gowns. But then the boat gets caught
in a glitter storm! Luckily, Buttercup calls out to some friendly
seahorses, who give the fairy princesses a ride to the Coral Castle
deep in the sparkly sea. But their clothes have been ruined
on the hazardous journey! Can they get ready for the party in time?
