In Marvel Land you play as Prince Paco (Talmit in English),who is on a quest to save Princess Luxy (Wondra in English) from the evil Mole King. All of the game's four levels take place in a fantasy amusement park, the "Marvel Land" of the title. Boss battles are performed at the end of the last level of all four worlds. They are unique in that they are played more like a minigame which can consist of rock paper scissors, musical chairs or even tug of war.
