Minotaur

The Minotaur 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. The Minotaur is immune to head stomps and Ground Pounds, due to his horns and thick hide. The Minotaur attempts to destroy him by picking him up and throwing him into the lava below their battleground. To defeat the boss, Wario has to stun him with a body slam or fire breath as Dragon Wario before picking him up and throwing him into the lava on either side of the boss arena.
