The Whale Killer.

He saw a tyrant of a soul prowler prowling around the edge of the feeding ground like a lion walking around a sheep farm. Nothing could threaten it. It was literally swallowing soul fragments and soul prowlers whole. Unaware or aware didn't make any difference to it. 

This soul prowler is almost a hundred times bigger than his current size. That means it is more than ten thousand times bigger than when he just came to the spiritual dimension. 

The size didn't daunt him. He said, "This is the perfect opportunity to use the whale killer."

He produced the maximum amount of tentacles that he could manage. This is 99 which is a lot. He is a hundred times bigger so this is to be expected. Then he brought the tentacles together to form a large spear. Next, he twisted them and shot toward the whale of a soul prowler. 

"What are you?" It asked.
