Rick and Morty (Wererabbit Transformations)

In the season 8 episode 4, Jerry runs over the Easter Bunny and starts turning into a wererabbit. Rick attempts to cure Jerry but this leads to the family getting transformed one at a time. Thanks to Noodles on our Discord server for providing the clip (and to everyone who told us about the episode). Scene transitions may be choppy, since the transformation was multi-staged:

The Curse Of The WereRabbit (Rabbit Transformation)

Thanks to Mike for recommending this goofy family-made video involving a man-to-lagomorph metamorphosis. 

If the cue doesn't work, go to 2:57.

Metamorphose (Rabbit Monster and Werewolf Transformations)

 Metamorphose is an anthology of short comics drawn in the late 1970s by Osamu Tezuka, the "Godfather of Manga." The fifth story is called "Woobit" and involves werewolves...and a rabbit.

A quick summary: after a werewolf gets killed, the demon that caused its lycanthropy infects a rabbit, so every full moon it becomes a wolfish monster ("wererabbit" would be incorrect, since "were" means "man"). 

Let's start with the rabbit's owner witnessing its transformation. Remember to read right-to-left!

The rabbit-wolf escapes into the wild and is tracked down by its owner. He's joined by a werewolf hunter who turns out to be a werewolf:

The owner and hunter finally track down the monster bunny. Witness their final battle:

Harey Podder: Say the Magic Word (Rabbit Transformation)

No points on guessing what Harey Podder: Say the Magic Word is a parody of! This is another very funny short by the very talented animator Stodoe.


And once again, we have the treat of looking through still frames of the transformation! Viewable here.

Fujitsu Commercial (Rabbit Transformation)

This Japanese computer commercial, starring heartthrob Takuya Kimura, features a somewhat rare lapin transformation...EDIT: Robin notes that "in Japan the full moon is associated with two rabbits on the moon pounding mochi...there are even foods associated with the full moon and rabbits."
You learn something new everyday! I certainly hope to come across more obscure Japanese transformations in the future.
