Nice, fun, and a bit creepy.
I don't know why, but something about the design reminded me of a flash game from when I was a kid. This was just under two decades ago, so my memories kind of hazy, but it involved a witch leaving a potion on the ground. She flew off, a guy acted on curiosity and impulse, and so ate the potion...which in turn turned his head into a pumpkin.
The game largely centered on finding her place to get an antidote.
Anyway, long story short, the guy gets there and explains what happened. She chewed him out for acting like an idiot and eating some experimental stuff someone left on the ground, and fixed him...and because she found him good-looking, she immediately told him it didn't work, and handed him another potion to "fix" him and...well you can guess the rest.
Anyway, great animation. I'll probably check it out later on YouTube so I can find the lyrics somewhere in the comments.
