Stuffy the 5th
From the Super Mario Wiki
Stuffy the 5th is the name of the 5th ruler of the Dolphinian empire. As he is deceased, he appears as a statue enemy in Wario: Master of Disguise during Wario's adventure in Blowhole Castle. Only one appears in the game where it guards the chest containing the Wandering Soul. He attacks by shooting lasers from his mouth. Wario could defeat him by becoming Cosmic Wario or Dragon Wario and firing into his mouth just after he fires, but before he closes his mouth again.
The fifth king of the Dolphinian empire had a short yet troubled reign, so his people commemorated him with this angry, angry statue.
