Wait for Boko to stand up on its hind legs to attack.

Get past Boko's amateurish telegraphed punch by ducking.

Quickly take his back.

Since Boko's limbs are so short, they can't reach his back.

Firmly apply a choke from behind. No matter how much strength he has, once the blood is cut off from his brain he'll collapse.

He's fainted ♥
