Muddie is a dark blue Mudraker with several dark green spot on his sail and wings.
When the player meets the Archaeologist on Mudraker Island, a lone Mudraker has taken an interest in him. The Archaeologist decides to train the dragon and names him Muddie. However, the dragon covers his dig site in mud and takes his pickaxe. While he is mad at first, the Archaeologist soon realizes that Muddie was just playing. To help calm Muddie down, the player brings Bing, Bam, and Boom to play with him, but only causes ruckus. The Archaeologist doesn't get mad though, and expects the dragons will tire out.
Muddie is mentioned in "Secrets of the Leviathan", where the Archaeologist states that he has been training with Muddie to learn how to fly dragons, which allows him to fly Phlegma's Snaptrapper, Snappy.
- Muddie is the only known tamed Mudraker, not counting the player's if he or she has one.
