Tormented by school bully Linus and ignored by busy parents, Max finds solace only in his Dream Journal, wherein he has meticulously crafted a vibrant utopian world. His ultimate creations are Sharkboy—a fierce vigilante raised by sharks after losing his father at sea—and Lavagirl, a powerful, fiery heroine capable of generating liquid flame. Max’s life takes a bizarre turn during a fierce storm when a real-life Sharkboy and Lavagirl crash through his classroom window, urgently whisking him away in a customized airship to Planet Drool.Upon arrival, Max discovers his fantastical realm is in total jeopardy. The pristine landscapes are decaying, and the vibrant colors are fading into monochromatic gray.

extraordinary friends, waking up back in his classroom with a newfound sense of confidence. He bravely stands up to Linus, sharing his journal and inviting him to collaborate on new dreams.
