Under the covers, they have little animals painted around the edges, one animal per plate:

A rabbit - contains an assortment of fresh-baked, dainty little cakes.
A fox - contains something black: squid and squid ink risotto.
A tentacle monster - contains jellyfish topped with century eggs.
A pigeon - contains an odd mix of grain and sugared rose petals.
A porcupine - contains slippery-looking udon noodles.
A . . . hideous cross between a cat and a pigeon - contains what looks like an assortment of random ingredients put together in a casserole.
A snake - contains some sort of reddish-orange stew.
