I'm not sure what these other yokels are going on about, but Captain Flamingo is a great cartoon! It's very cute and silly, somewhat in the same manner as Powerpuff Girls, with a touch of Fairly Odd Parents thrown into the mix as well.
The basic premise of each show is that Flamingo - who became a hero to help "'lil kids everywhere," must come to the rescue of kids with typically silly problems, rather than serious ones. Flamingo must use his wits to solve the problem at hand, often aided by his best friend Lizbeth Amanda, who has a secret crush on him.
It's just a cute little show that doesn't take itself too seriously, and if you have any kind of silly sense of humor, you'll enjoy it. With Captain Flamingo, silly often takes the day, and as a huge fan of the show, I wouldn't have it any other way!
