    One day, our hero Boink was having a nice day out with his girlfriend Ploink. Suddenly, an evil wizard appeared and kidnapped her! Not only that, but the wizard cast a wicked spell on Boink that caused him to bounce uncontrollably!

    The wizard disappeared with Ploink just as suddenly as he appeared, but not before dropping a strange map amidst all the confusion. The map led to an ancient Maztactl temple - this must be the wizard's hideout!

    And so, Boink decides to set off on a voyage to the mysterious temple. Will he be able to break the spell and reunite with his girlfriend?
