Upgrade for crocodiles

I feel bad for killing crocodiles just for the teeth so my solution is that a bird variant comes and cleans the crocodiles teeth as the crocodiles opens wide, as the bird is cleaning, it has a change to make a crocodile tooth to chip off that players can collect. With birds already added into the game I can imagine that if can easily fit into origin realms.

Make crocodiles breedable, maybe when you feed 2 crocodiles fish, one crocodile will go to land close to water and make a burrow similar to the one that crabs make, the crocodile will be protective of the area and when it is ready the crocodile babies will come out and hatch. I think this will show the nicer and more affectionate side of crocodiles as it will show mother crocodiles caring for young.
