L'histoire raconte l'aventure de Duck Dodgers à la recherche de « l’Illudium Phosdex ». Cet élément chimique rare, atome constitutif de la crème à raser, ne se trouve plus que sur la mystérieuse « planète X ». Daffy Duck, accompagné de son « Cadet de l'espace » (Porky Pig), fait des recherches sur un tableau et déduit qu'il faut passer par toutes les planètes marquée d'une lettre, et ceci par ordre alphabétique, pour aboutir « naturellement » à cette planète X. Daffy Duck finit par y atterrir. Il en prend possession au nom de la Terre, au moment où Marvin le Martien fait de même au nom de la planète Mars. Les deux champions planétaires vont devoir s’affronter en un combat où la ruse compte encore plus que la force brute. Au cours de leur recherche de la suprématie sur la planète, Daffy et Marvin se menacent chacun d'un pistolet désintégrateur. Quand Marvin tire, il désintègre Daffy en particules atomiques. Mais heureusement Porky le « réintègre » grâce à un pistolet du même nom. Depuis leur vaisseau respectif, Daffy et Marvin s'espionnent ; puis chacun dirige sur l'autre une arme extrêmement destructrice. La planète est peu après complètement détruite, sauf un petit morceau qui flotte dans l'espace et auquel se raccrochent les trois protagonistes. Tandis que Daffy-Duck Dodgers crie victoire, Porky conclut par un désabusé « Oh la belle affaire.
The film's content is derived from three previously released animated featurettes Disney produced based upon the Winnie-the-Pooh books by A. A. Milne: Winnie the Pooh and the Honey Tree (1966), Winnie the Pooh and the Blustery Day (1968), and Winnie the Pooh and Tigger Too (1974). Extra material used to link the three featurettes together was added to allow the stories to merge into each other.
In order to conquer mankind and rule the universe, King Horn sets out to find all seven of the Dragon Pearls. With two of the seven already in the evil king's possession, it is now up to the remaining five owners of the pearls — Son Goku (Son Gohan is the owner, Son Goku is his adopted grandson), Piggy, La Ping, Turtle Man and Seetoe — to destroy King Horn and his two powerful warriors, Zebrata and Maria, before it is too late.
It consists of six stories from the fairy tale tradition, all performed by the Muppet characters and narrated by Rizzo and Gonzo at the Muppet Theater:
The short opens with introductions of Miss Cud (a cow who is the school teacher), Beans (who is caught defiantly eating from a jar of jam), Porky, Oliver Owl (who are both shown at once), and Ham and Ex (twin puppies). Little Kitty is absent from this sequence. A poster is shown explaining that the school children are sponsoring a musical and recital for the benefit of teachers and parents.
There is a mouse invading Porky Pig's house, but so far Porky's attempts to rid the mouse have failed. Porky gets a cat to catch the mouse, only for the cat to get bound and launched out of the house. Next Porky borrows a mountain lion, but the mouse has petrified and stuffed the lion. Next Porky hires a gangster cat, but he leaves straight after a bonk on the head with a bowling ball.
Manor Farm is a formerly prosperous farm that has fallen on hard times, and suffers under the now-ineffective leadership of its drunken and aggressive owner, Mr. Jones. One night, Old Major, the prize boar and the second-oldest on the farm, calls the animals on the farm for a meeting, where he compares the humans to parasites and encourages the animals to break free from their tyrant's influence, while reminding them that they must hold true to their convictions after they have gained freedom. With that, he teaches the animals a revolutionary song, before collapsing dead mid-song to the animals' horror.
The farm of the Kahlow family is struck by disaster: although it mated with neighbor Grossig's white swine, their white sow delivered black piglets, a sinister omen. The old Grandmother Kahlow interprets this as a sign from heaven not to join the nearby Agricultural Cooperative, although her grandson Claus - who wants to marry Grossig's daughter, Irma - wishes them to do so. Grossig supports her, and declares the piglets to be "unchristian", although the village priest resents that. But then, Father Melcior is also afflicted by the phenomenon: his sow, Cleopatra, delivers black piglets. He decides that the Old Kahlow is correct, and plans to start his own, Christian Cooperative, "with white pigs only". The villagers are very much upset. Wild rumors, fanned by superstition, take hold among them. In the Cooperative, the young animal breeder Inge discovers that Lubanski, the pig herder, secretly trained his black hog Brutus to sneak through fences, so he could mate with the farmers' sows. Lubanski, who greatly enjoyed the pandemonium, agrees to reveal the truth to the farmers. They all agree to join the Collective.
