Slowly, and cautiously, Neve and Erin walked into what could only be described as an obvious boss arena.
Erin, still mad for some reason, was ahead a few steps. Neve, holding a rocket launcher that was almost bigger than she was, waited behind her.
[... If I know anything about boss design, as soon as we reach the middle of the arena, the ground will start shaking and-]
As soon as Erin reached the middle of the arena, the ground began shaking.
"What is happening!?" Erin asked. "Stay back," she told Neve. "Perhaps- why do you look so unsurprised?"
[Sorry, this is just a little too cliche for me to be shocked at all.]
Erin narrowed her eyes a little at Neve before something bursting out from the ground ahead pulled her attention away.
There it was. The boss of the Second Floor. A long, thick, and stiff pink worm came out from the ground, stretched up into the air, and gave a mighty, shrill screech.
