The Beats Rat gallops toward Isaac, he quickly stands out of the sand and grabs a stone that he piles beside him and throws it at the Beast Rat.
The Beast Rat dodged the stone to the right and jumped toward him, its mouth wide open ready to bite Isaac head off. Isaac timed it well as he grabbed a big stone that he couldn't clench properly in his hand and punched forward, not to the face of the Beast Rat, but inside its mouth.
Due to the abundant experience he has in the past, he was able to devise a plan at the last minute in this helpless fight.
Once his hand enters the Beast Rat mouth he uses his weight and all his strength, sacrificing his right and shoves it deep into the beast throat. At the same time, he grabbed another giant stone with his left hand and bash the Beast Rat head.
