Cockroach Land

On Floor 22, a man and a cockroach were progressing at a steady pace. 

They would encounter enemy cockroaches that would block their way from time to time, but Josh would make quick work of them. However, the more they walked and the more monsters there were. 

The packs of a dozen enemies grew to 100 of them at once! He had to somehow prevent them from reaching his companion. The way he did it was to charge ahead to grab the aggro. 

It worked wonders initially, but at some point, it just failed. The backline would simply ignore Josh once he was already surrounded. Instead, they would scuttle toward the friendly NPC. 

This guy had no survival instinct whatsoever! It would just stand there in place, shivering endlessly. What kind of useless cockroach was this? Their species was supposed to be speed itself! (for their size anyway)
