When the Warden roars on bedrock, its tendrils will move a bit differently from its head, which does not happen on Java. Its head will also sometimes glitch while roaring and bend upwards into its body.

Step to Reproduce:
1. Spawn a Warden
2. Anger the Warden until it roars or run the command /playanimation @e[type=warden] animation.warden.roar
3. Look at the wardens ears/tendrils when it roars, they will move differently than on Java

Expected Result:
The roaring animation is the same as Java

Observed Result:
The roaring animation doesn't match and will sometimes glitch

Incorrect Tendril Movement:
