Mel Blancwas gong to voice Gideon but Walt decided that he should remain a silent character akin to Dopey so all of his lines were cut out and only 3 hiccups that were recorded by Blanc remained in the final cut, though he was still paid for his work.
Foulfellow and Gideon were supposed to meet Pinocchio a third time, and be caught by the police. Cutting this effectively made them Karma Houdinis.
There was to be a Dream Sequence where Geppetto would tell Pinocchio a bedtime story about his grandfather, a mighty pine tree.
Originally the donkey Lampwick was supposed to join Pinocchio and Jiminy in their escape from Pleasure Island but he is captured by the Coachman's minions, as he is being carried away he says "Go on without me, it's no use I'm a goner", some storybook adaptations keep the scene.
The movie was originally going to take place around Christmastime, which meant that it would also be snowing. Walt Disney nixed the idea because he wanted the movie to be enjoyed year-round.
