The Bug:

Snifflets, or baby Sniffers, share a slightly different and inconsistent model on Java vs Bedrock. Java Snifflets have a smaller, more proportionate head. On Bedrock the head is larger like most other baby animals.

Here's how Snifflets look on Java, notice the proportionate head:

And here they are on Bedrock, with a larger head:

Steps to Reproduce:

1. Summon a Snifflet on java, and take notice of its smaller head
2. Do the same on Bedrock, and see how its head is bigger
3. Bedrock's is more align with other baby animals in the game
