Ronald McDonald and the Adventure Machine (found McDonald's animated video; 1987)
From The Lost Media Wiki
Around 1987, McDonald’s released an eight minute VHS called Ronald’s Adventure Machine, which was only available for viewing at birthday parties at the titular restaurant. The video was animated by Sinnott and Associates in Chicago.
Plot
Not much is known about it except that Ronald McDonald and his friends go inside the "Adventure Machine" except The Professor.
Availability
Since the tape was only made available for viewing at birthday parties at the restaurant, no footage of it has resurfaced to the public and no copies of the tape are known to exist. However, several animation cels from the video have been made available online from the "FilmingInMcDonaldland"'s Facebook page.
