Kid Klown in Night Mayor World is an action platformer for the Nintendo Entertainment System. In Japan, it is originally a Mickey Mouse game called Mickey Mouse III: Yume Fuusen.

Once upon a time there was a series of Mickey Mouse games on the original Nintendo. Most were translated faithfully, but a few were altered due to licensing agreements. Mickey Mouse III - Dream Balloon (aka: Yume Fuusen) was one such game - in English-speaking countries it was called "Kid Klown", with (in my opinion) rather hideous graphic changes and a completely different story.
This patch translates the game into English, so you can see what Disney felt they weren't being paid enough in 1992 to show you.
(*Yes there's a prototype version that was translated, but the English was pretty terrible*)
