The Nimbus is a Mount summoning item that can be bought from the Tracker after finishing the twelfth contract. When used, it summons a rideable Wyvern.
The Wyvern can fly quickly in any direction and hover, but requires the arrow keys to be used to lift it off the ground. After about ten seconds of being constantly in the air, it will begin to descend automatically, and must land on the ground again to reset its flight time. It has a top speed of 82 miles per hour.
- The description of the mount is a reference to the Youtuber Happy Days.
- 220.127.116.11: Is now sold by the Tracker instead of being dropped from Wyverns.
- 18.104.22.168: Introduced.
