Pufferfish spikes model seems to be broken

The bug

As you can see in the images, the bottom front spikes of the medium pufferfish are messed up and the front left spickes of the big pufferfish are missing.

The bottom and top spikes of the medium pufferfish are not using the right UV map coordinates on the texture.

To reproduce

Use the following command to inspect the pufferfish model.

Medium

/summon minecraft:pufferfish ~ ~ ~ {NoAI:1b,NoGravity:1b,Invulnerable:1b,PuffState:1}

Big

/summon minecraft:pufferfish ~ ~ ~ {NoAI:1b,NoGravity:1b,Invulnerable:1b,PuffState:2}
