The Super Happy Magic Forest is the friendliest, most frolic-filled place in all the world, but very occasionally something comes along and disturb the peace. That's when our five brave heroes step up to save the day-there's Blossom the unicorn, Twinkle the pixie, Herbert the gnome, Hoofius the faun, and a plucky little mushroom called Trevor. In this adventure, the five heroes go diving for Candy Coral in Lake Sparkle and find more than they bargained for-a fishy-looking creature called Foam. It's the start of a brand-new seafaring quest! Time for the gang to find their sea-legs and set sail on an adventure to the underwater city of Fishopolis!
