Is your feature request related to a problem? Please describe.
It is not a bug, it is a small aesthetic addition that I do not know if it is already implemented in Pokecube

Describe the solution you'd like
It is a simple and useless but aesthetic change.
The idea is that flying pokemobs (which always move by flying) have an option or button that allows us to choose if we want them to move by walking or flying.
It may seem like a useless addition, but I think a Dialga, for example, would look great if you could see its flying animation as well as its walking animation.

Describe alternatives you've considered
If it is not added via button, there must be some behavior or AI that makes the pokemob detect whether it should walk or fly

Additional context
I honestly don't know if this feature is already in game but I recommended it in case it wasn't there.

that button already exists, go look in the AI tab of the inventory, one of the buttons does this
