Mickey Mouse III: Dream Balloon
Mickey Mouse is working part-time selling balloons in order to buy a present for Minnie, whose birthday is a few days away. He gets news from Pluto that Minnie cannot wake up. He sets off to visit her, only to find that she has been trapped in a nightmare. Now, Mickey must journey into Minnie's mind in order to free her from the nightmare.

Kid Klown in Night Mayor World
Kid Klown and his family are on their way to perform in a circus when they meet the magician Night Mayor (a pun on "nightmare"). He asks Kid Klown to help him open a treasure vault, but Kid Klown, having been warned about the evil magician by his parents, refuses. Not willing to give up so easily, Night Mayor kidnaps Kid Klown's family and dares him to follow him into his world if he ever wants to see his family again.

Gameplay
The player character, Mickey Mouse/Kid Klown, carries balloons with which he can attack, jump higher, or float. Including the introduction level, there are seven interesting levels throughout the game, each with its own unique theme. At the very end of each level, there is a bonus stage. The player is able to collect extra lives and extra energy in the bonus stage.

The stage select screen in the original game features the song "It's a Small World" in the original; it was changed in the American release. In the original, the boss in the first stage is one of the vultures from The Jungle Book, while the Kid Klown version features an owl. The third stage (based on the folk tale Jack & the Beanstalk) has Rumplewald the giant from the cartoon Giantland as the end boss; the American version replaces him with a cyclops. The Horned King from The Black Cauldron is the final boss in the original; Night Mayor is the final boss in the Kid Klown game.
