Hiyoihoi

Hiyoihoi, also written as Hiyohoi, is the third boss in the game Super Mario Land. He evolved from a Tokotoko and resembles this enemy in appearance, except that he has legs. Hiyoihoi is in charge of the Easton Kingdom. During Tatanga's invasion of Sarasaland, Hiyoihoi came under Tatanga's control.

In battle, Hiyoihoi attacks by throwing Ganchan boulders at Mario. To defeat Hiyoihoi, Mario has to fire ten Superballs at him while avoiding being hit by the Ganchans. Alternatively, Mario can simply jump over Hiyoihoi and activate the switch behind him. Either way, Mario is awarded 5000 points for defeating Hiyoihoi and is allowed to progress into the Chai Kingdom.

In the Super Mario Land manga, Hiyoihoi is the boss of Easton Kingdom and is disappointed in seeing how incompetent his Tokotoko, Batadon, and Ganchan minions are, becoming more mad in seeing how Tatanga trusts the Kumos and Suu more than him in taking down Mario. After Suu-chan accidentally kills the Tokotoko and Batadon, Hiyoihoi blows a fuse and, armed with a Gatling gun, starts to shoot Bullet Biffs at everything, only managing to kill the Kumos. Mario saves Suu-chan by tackling her away from an incoming Bullet Biff, gaining her trust and gratitude. The two then face Hiyoihoi on his floating base and, after crossing a strange maze, reach him and defeat him by tossing more Superballs at once. With Hiyoihoi's defeat, the entire base disappears, and Suu-chan with it.

In Super Mario-kun, Hiyoihoi appears in the last chapter of volume 3. He occupies a room in Bowser's Castle with the Tokotoko and Batadon. He attempts to squash Mario with the Ganchan, but Mario forces Yoshi to eat them and toss him at the moai like a bowling ball, striking them down. Hiyoihoi and the others get back up and group together to form a boulder to try and stop Mario. Later, when the heroes are fighting King Totomesu, Hiyoihoi and his soldiers step between them, claiming that Totomesu has no right to take "their prey", starting a fight between them and letting Mario, Luigi, and Yoshi escape.
