A Japanese dish consisting of rice, fish eggs and squid. While a traditional ikki-don dish serves the squid in slices, odori-don serves the squid fresh and whole. This means that gourmands can pour soy sauce over the fish, which has the effect of stimulating the muscles inside it and appears to make it dance in the bowl.

This effect occurs due to the high sodium content of soy sauce. The sodium contains ionic charge which can be passed to the squid's nerve cells. As the squid is fresh, its cells are still working and active, leading to the spasmodic activity that diners enjoy.
