I liked it, but I can't deny that could definitely be jarring at times. My sister couldn't stand it on her end. It reminded me of that "Mama Luigi Reanimate" collaboration from a little while back. It jumped around a bit, but it was definitely a unique concept. I think it's fine for a one-off!
Just finished the episode, and yeah... I never got over the art style thing. Probably my least favorite Bob's Burgers episode that I can remember.
