The Warners show up an a cartoon from the 1930's. They have an adventure with the animated character Googy Goop who is a parody of Betty Boop.
The two Warner Brothers Yakko and Wakko and their Warner sister Dot had been created in the 1930's, but their cartoons were too screwy for the general public to handle.
The three Warners were locked up in the studio water tower until they escaped in the 90's.
There, they run wild, causing chaos everywhere!
