Colonel Bleep

Colonel Bleep was an American animated series that aired from 1957 to 1960. It was notable for being one of the first color cartoon series produced specifically for television. The show featured very simple, limited animation techniques.
The main character, Colonel Bleep, was a small, alien-like being from the planet Futura. He had a round head with a single antenna and could fly. The Colonel protected Earth, particularly the Florida region, from various threats.
Colonel Bleep was usually accompanied by his two sidekicks:

Squeak, a cowboy puppet boy
Scratch, a caveman

The trio would work together to thwart the plans of villains and solve problems, often using Colonel Bleep’s advanced Futuran technology.
The series was produced by Robert D. Buchanan and was relatively short-lived, consisting of about 100 episodes. Despite its brief run, it holds a place in animation history as an early example of made-for-TV cartoons and for its use of color.
