In this episode of Planet Unicorn, the boys (Feathers, Cadillac, and Tom Cruise) take a trip to beautiful unicorn beach, where they encounter an evil, fire-blowing "watercorn" who traps them in his poorly decorated underwater torture cave. The horror! Will they be deprived of pretty, pretty rainbows and Boba drinks forever and ever (gasp!), or will someone (obviously not Tom Cruise) save the day? Warning: highly addictive.
