Replace the size number with each animation key. You said you made it look like fox ears, yes?
The animation follows the original ears. All you have to do is either replace the size they have in the animation keys, or add it.
I will make my words easier...
(Be sure to dupe the animation first though in case you mess up)
Animation doesn't have fox shape ears. Has normal ears.
Add animation key for the fox shape ears you have IN the animation.
You only need TWO animations typically to keep the shape. One at the start, one at the end.
It SHOULD work.
If not then just remake the animation with screenshots of every key that's needed with the fox ears you did.
