In Luceti, characters can speak with the local creatures! Most of the animals talk, and some characters have even spoken to fish. Insects are generally too small to be heard, though characters who are tiny might hear them.
They're generally simple-minded, and their personalities are fairly non-descript. Characters can try to befriend them if they wish, and some can be tamed enough to keep as pets, but remember these are wild animals, not domestics like you might be used to. Also, their voices cannot be understood over the journal; anyone trying to communicate with them will only hear their natural noises. Additionally, animals who don't usually make sounds will be either silent or very quiet and will not speak often.
