Animation by Paul Strong (Donkey and Worm/Serpent Transformations)

Digital animator Paul Strong has provided links to two of his shorts. Both are NSFW.

The first is a partial donkey transformation:

The second species is harder to describe...make your own guess!

I think it's a cross between a worm and serpent...

In any case, Paul's Patreon is here. 

The Bookworm Turns (Age Progression)

Our friend Caleb suggested featuring this classic MGM cartoon from 1940, which features Dr. Jekyll switching the brains of Poe's raven and a literal bookworm. He compensates by making the bookworm grow into a giant brute. Unfortunately the only video online is a German dub (the original starred Mel Blanc), but we'll take what we can get, since this is a cartoon transformations from animation's golden age.
