With the Wolf cubs and Cave lion cubs getting ridable adult forms, the question arises for the baby mammoths. Obviously an adult mammoth might be a BIT big to ride or have collect things or perform other functions in the village, but what about a "teenage mammoth" that's more in line with the other mounts. Still probably the biggest but not as gigantic as their adult forms.
As far as functionality, I like the idea of either auto watering/crop harvesting or when riding they can pick things up for you. As you ride through an area the mammoth will harvest seeds and gather forage for you so you don't have to dismount. Stuff like taming and fishing you still have to do on your own though.
