Beefne is a member of the Brown Sugar Pirates in Wario Land: Super Mario Land 3. As the leader of Mt. Teapot, he is the second boss Wario needs to overcome to reach Captain Syrup's treasure. Beefne is immune to head stomps and Ground Pounds, due to his horns and thick hide. Beefne attempts to destroy him by picking him up and throwing him into the lava below their battleground. To defeat him, Wario has to throw him into the lava instead.
