The Baggy Pants Cartoon cat is little known. Thirteen episodes were produced by De Patie-Freleng. They were shown on Baggy Pants and Nitwits (NBC 1977). The cartoons only contained sight and sound (no voice) and were a bit like the Pink Panther but less clever.
Here is another video. Like the one above it is poor quality I am afraid. I can’t find a better-quality version:
Baggy Pants dressed like Charlies Chaplin’s Tramp. He had a moustache and a cane. Baggy pants remained optimistic and cheerful despite being rebuffed by everyone as he tried to make friends in various settings including:
a haunted house
on the beach
on a movie set
at a circus
The Nitwits were based on a park bench character in TV’s Laugh-In. That’s it folks…
