Literary Toons: Pontoffel Pock, Where Are You? (1980)

DePatie-Freleng's adaptation of Dr. Seuss' Pontoffel Pock, Where Are You?, which premiered on ABC in 1980, was one of the last entries for the studio before it was acquired by Marvel and rechristened Marvel Productions a year later.

In addition to composing the music, noted tunesmith Joe Raposo also does some acting, as he plays the owner of a pickle factory where Pontoffel Pock (Wayne Morton, Fred & Barney Meet The Thing) had been employed very briefly at the start of the show.

I never saw it, so there's no rating. As you'll doubtlessly notice, Universal owns the rights.
