Emmy hatches a plan to have Max, who is anxious about his first day at their new school, "practice" by attending the School in the Sky with their dragon friends in Dragon Land. When the children find they are not naturals at certain dragon activities, the wise teacher Quetzal is there to encourage persistence. In, "Max's Comic Adventure" Max shows off his favorite superhero comic book, "The Adventures of Mondo Mouse. " As everyone takes turns looking through the special 3D glasses, they start to see strange picture symbols all over Dragon Land. Figuring out each clue eventually leads them to a bright light coming from a cave, where they discover a caged Mondo shining his mega-mirror! Just as in Max's book, he has been captured by the Cat Napper. To free him, the group tries various combinations on the lock keypad, which resembles a hopscotch board. Zak's "hopscotch skip" does the trick, and Mondo thanks them all by taking them for an exciting ride on his rocket skateboard.
