Looking for Help with Mobs and Animals!

[Saracalia]

I am just wondering if anyone can help me with mobs an animals for my texture pack! Because I don't have Paint.NET on this computer, and I can't really download anymore programs onto this computer due to how much space I am trying to preserve for other stuff!

If you do decide to help, I will give you  some credit for it. It is only the mobs and animals that needs to be done. Thank you.
