Jim’s Red Book “Alexander the Grape” (by HensonCompany)
Did you know Jim Henson did animation? Me neither.
Anyway, this is an attempt he did at cartooning called Alexander the Grape, about the titular character (voiced by Jerry Juhl) wanting to become a watermelon to give the bully watermelon Freddy the Fierce (voiced by Jim Henson) a smack to the face.
It was never finished but some people found remnants of this project (storyboards, soundtrack, incomplete film) and spliced it together for the internet.
