The three sizes of Dragonite!
Sad that Cobblemon doesn't have size variations in the models? Yeah, me too. I understand why it likely won't be implemented, but I wanted to take my shot at making it work anyways. Here's this. You have normal, which is the default cobblemon size. Then you have one size down, small, and one size up, large.
Currently there is no way to check what size without viewing the entity NBT.
