Wandering trader animals

It would be awesome if a different animal spawned with the wandering trader depending on which biome he spawned in. I know ostriches are being added and that could be one of the animals or the mule which is also a great animal to choose. Camels are not a thing but if they will be they would also be a great mob. In fact if we do ever get boat wandering traders dolphins would be a great choice. pandas and polar bears maybe not so much but it would still be cool.
