i think ukagaka are more like bonzi buddy as Zilvra said, and the sheeps are more like shimeji. difference being one has more of a personality as it talks to you and all that, while the other kinda wanders and does wot it do.

there is, however, at least one member of the english community that's looking to bring shimeji behaviors into ukagakas, so that might be a fun possibility in the future.
