The title character
Captain Carlos was a series of Flash-animated educational shorts on Playhouse Disney. In every skit, Carlos would want to eat a healthy food, but his sister Maria pushes junk food upon him. Then, the narrator explains how the junk food can affect your body, and how the healthy food does vice-versa. The skits have not aired since at least 2008.
Avaliability
A handful of the skits are avaliable in Spanish on YouTube, as well as a "rough cut" of an episode on Vimeo . Most of them, as well as all english versions of the episodes, are currently lost.
