This is my Sushi inspired model from Paper Mario 64, one of the 8 partners you can befriend.

Sushi is split into 6 main parts:

Main body, split in half with a connector piece.
2 Side fins
Hair and back fin
Mouth, has inserts to fit into the body
Eyeball, has slots for the eyes and sits in the top body piece
Eyes, 2 that go into the main eyeball piece
Cheeks, 2 which go into the side of the body face
Base, optional but holds sushi upright

Everything here prints without supports and on standard settings, 0.4mm nozzle
