Hiyoihoi is the third boss in Super Mario Land, and a servant of Tatanga. He is a giant Tokotoko with legs.

Tatanga assigned him to guard the end of Easton Kingdom and the entrance to Chai, but Mario defeated him, and he was destroyed in an explosion.

Hiyoihoi attacks by throwing Ganchan boulders at Mario. To get by Hiyoihoi without taking damage, Mario must jump on the Ganchans and use them as platforms to reach the switch to destroy him, however, this is extremely tricky to time. However, there is a mushroom right before Hiyoihoi, that is accessible even from the checkpoint, so that if Mario touches Hiyoihoi by mistake, he will get shrunk, but can still reach the switch.
