For my boyfriend's birthday I farmed him a Disgusting Oozeling (3 days!) so he could turn his firehawk green.
The green firehawk mount is not technically in the game however you can temporarily turn an orange firehawk into a green one if you have the pet. He loves the green one so I painted this. :3
Inspired by this screenshot I took of him: [link]
These firehawks are mounts in World of Warcraft.
