7. Thundering Onyx Cloud Serpent

It's a snake in the sky!

Cloud serpents were a new type of flying mount introduced in Pandaria. We had the chance to ride around on massive dragon snakes in the sky. It was awesome! After doing a long reputation grind and getting the ability to fly these things for good, you could head out to Timeless Isle in search for this mount.

Huolon was the most popular rare mob on the island and was usually downed in a matter of seconds after he spawned. There were often 100-200 players spawn-camping him, hoping to get this mount to drop. Now you’ll probably need to get a pre-made group together since Timeless Isle is deserted.
