Rotation like an axolotl or squid.

So I've been developing a mod with a swimming creature in it whose model I would like to be able to freely rotate in the water like an axolotl, squid, or dolphin.

I am well aware that this is not implemented in the basic settings of Mcreator but for those with ample coding prowess, I inquire on how one might go about accomplishing such a thing?

In other words, if you know how to code could you tell me how to get a model to rotate in the direction of movement.

Anyway, that is my question, as I have not found any answers to it elsewhere.
