The Brownies find an egg, just as a duckling hatches out of it. The Brownies glue the egg back together with the Wizard inside, but before they can release him, the mother duck returns and takes control of the egg. When the Wizard breaks out of the egg, the duck thinks he is her baby. The other Brownies have to go find the real duckling to return it to its mother.
The Brownies [Wizard; Brainy; Muddle; Droopy]; Splooks
The Wizard warns the other Brownies that they should stay inside the day after Halloween to avoid goblins and witches. The rest ignore his advice and go exploring. They find the Splooks, who live underground and only go out on Halloween to scare people. The Splooks are frustrated when the Brownies aren't scared of them and take them to see the Grand Splook. They inadvertently insult the Grand Splook and have to flee back to the surface.
