The Disney Afternoon - Bumper Collection (1990-1994) 

For the first four years of The Disney Afternoon syndicated TV block, Disney used these cool little animated bumpers to segue between commercial breaks. Starting with the 1994 Season, they switched to a more boring, generic format.
The first year, they used a frog as their mascot. The second year, the classic Belgian comic strip character, Marsupilami would appear in the bumps. And in the third year, various characters would appear, including Goofy and Bonkers. Interestingly, both Marsupilami and Bonkers appeared in bumpers long before their respective cartoons aired.
