It’s day three of the Unicornicopia Celebration, which is traditionally celebrated by the unicorns with a big pool party. But when Shani and Polly get there, they find the pool has been sabotaged! Shani and Polly decide to bring the Unicorns to their world instead for the ultimate water park party! Although some unicorns may feel like Polly and Shani don’t belong at their pool party, the Smith Family Waterpark is a place where EVERYONE can have fun in the sun!
