The right/left ears, front legs, and back legs of a polar bear cannot be independently retextured

The right/left ears, front legs, and back legs of a polar bear cannot be independently retextured from one another, making them always look the same, limiting the player's resource pack creativity.

Steps to Reproduce:

1. Download and apply the following resource pack:
   PolarBear.zip
2. Spawn a polar bear

Observed Behavior:

Both of the ears, front legs, and back legs will look entirely red, despite the player seemingly only modifying one of each in the UV map.

Expected Result:

Only one of the ears, and front/back legs would be altered, since that is what the player intended to change. The current behavior is unexpected and not resource pack friendly.
