Jack and the Beanstalk

A fairy tale character who is about to flunk out of fairy tale school, Jack must perform a heroic deed by Monday or fail miserably, just like his father before him. Anxious to make good, Jack sells his C.O.W. (Computer of Wonder) for a handful of magic beans and a mysterious book that records his adventures as he's having them. Accompanied by his sidekick Grayson -- a goose who ate a bean and underwent an amazing transformation -- Jack climbs the magic beanstalk to recover the fabled Harp of Destiny from the evil Giant who lives in the sky.
