How to Beat King Hippo in the Nintendo's "Mike Tyson Punch Out"

King Hippo seems to be invincible in "Mike Tyson's Punch Out!" until you discover his weakness. Unlike the other boxers in the game, you can't damage King Hippo the normal way. His only vulnerable point isn't immediately obvious. You have to dodge his punches until you get the chance to make him reveal his bandaged navel.

Dodge King Hippo's punches by pressing left or right on the directional pad. Wait for him to shake back and forth and then raise his fist over his head while opening his mouth.

Punch him in the mouth by holding up on the directional pad and pressing the punch button. King Hippo's shorts will drop and he will stop attacking to pull up his shorts.

Punch him in the belly button until he covers it with his fists.

Repeat until he's down for the count.
