Ronald McDonald and the Adventure Machine

This was a short film that was only played at the birthday rooms located at certain McDonald's restaurants for a certain number of years. It was not made available on home video for the public to watch, and eventually McDonald's decided to stop showing the short at the birthday room locations of the restaurants. The short was for a while a lost short film as no copies of the short were known to exist until a copy was found in 2019.

Spin-off from McDonaldland (1963)
