Discolored Llama

It was raining in my minecraft world while I was playing with a friend of mine. We suddenly encountered a Llama with a few glitches. Once it was a weird gray with no face. Then my friend got off and it became red and green. Nothing could fix this poor Llama. Unsure if this has happened before or not. Just thought you should check it out. (Note: Please use "Llama Fixes" in next updates description if you see this. Thank you!!! 😄).
