Snurgle

The Snurgle is an enemy in Spirit Tracks. It can only be found while riding the train, and it resembles a small flying elephant. Link can blow the whistle at them to scatter them away, or use the cannon later on to shoot them out of the sky. It takes only one shot with the cannon to defeat a Snurgle. If the train is carrying cargo, such as fish, a Snurgle will attempt to steal the cargo instead of attacking the train. This bothersome act occurs when Link is trying to transport 15 fish to a woman in Hyrule Castle Town to recieve a Force Gem. A larger, stronger variety called a Snurglar appears in the Fire Realm.
