Odori-don - The Dancing Squid Bowl

I stumbled across a video (there are several) that shows a Japanese food dish that features a (dead) squid that is activated to "dancing" when soy sauce is poured over it.  Interesting dishes like this are part of how to help make a setting diverse and facinating.  Add some to your homebrew to keep the players on their toes and to keep them feeling like they are traveling to interesting places.  No need to tell them right away that the squid is definitely dead.
