Two cartoons for which I have an odd sentimentality had a similar protagonist and yet were at polar extremes.

The New Shmoo featured a squeaky transforming blob that led a group of teens on mysterious adventures – one of many Scooby Doo derivatives.

The Barbapapas were blobs as well, but pink and but did not follow such inane narratives, instead offering a simpler child-like perspective on solving environmental problems.
I was loyal to both, passively thinking they were somehow affiliated. The truth is that The New Shmoo and Barbapapas were just a blip in pop culture, like a girl-cop buddy show.
