Nautaloss appeared in 2016 video game called Yo-Kai Watch 3. Nautaloss (Japanese: ナンモナイト Nanmonito) is a Water-attribute, Merican Yo-kai of the Slippery tribe.
Nautaloss resembles a cream-yellow spiraling sea shell with four fuchsia stripes that move to the center of his shelled body. He has small black arms and oval eyes with green sclera.
Those possessed by him suddenly say "I have no regrets" about everything! His effect makes people say..."There's really people that just burst out that sorta thing, huh" and stuff like that.
