The nine human-craig monsters and the nine humanoid monsters rushed towards one another and collided. The humanoid monsters were sent flying by the collision which clearly indicated that the human-crab monsters were stronger than the humanoid monsters.
The humanoid monsters who didn't have mouths didn't scream in pain after such a powerful impact. They quickly stood up and rushed at their enemies again but due to the strength difference, the human-crab monsters had an overwhelming advantage.
Using the high temperature pincers, each human-crab monster grabbed their target and the human upper body beat the shit out of the humanity monsters. Each punch broke a bone of the humanoid monsters and the pincers were quite literally cooking their flesh slowly.
[Hahaha, good boys! Beat them up! Teach them a lesson! Don't quickly kill them but thoroughly beat them up!] said the Deity who created the human-crab monsters.
