An earth pony called Turnip Seed, a friend of Flash Point, wants to spend the winter as a pool toy at the water park. In order to avoid the perils of Flash's previous adventure, they both sign a contract with the water park. In return for entertaining the visitors, the park employees will keep them safe from harm. Flash Point and Turnip Seed then find out the hard way what life as an inflatable pony is like, as their so-called winter holiday turns out to be something more than they had expected.
