We begin the story with Don Quixote's infamous battle with the windmill, which has the unfortunate result of sending the Don out of his book and into Toyland where (surprise surprise) he decides that all of the toys are evil monsters which must be destroyed. (And he's not even a religious zealot.) The Blockheads notice the erratic knight and decide to send him to Gumby's farm, hoping he'll cause some delightful havoc. He mistakes Denali's house for a castle and Denali for a horrible monster. Fortunately, the man of La Mancha is easily overwhelmed by ice cubes, and Denali deposits him before Gumby to do with him what he will. Gumby tells the insane man that his wizard (Professor Kapp) will give him magical powers to fight evil (use some sort of device to end his insanity). And so, another classic story completely ruined by Gumby's well-meaningfulness.
