>Investigate the Skull's Old Room

The giant louse doesn't seem like it's going to be any help just yet. You opt to see if anything replaced that broken skull thing, now that the little guy's working with the spine.

You enter examination room III...
...Only to be met with the one sight you absolutely cannot handle. The one thing that makes your entire body itch just to think about.

You get only a faint glimpse before recoiling, but it's enough. Your mouth goes dry as you try not to heave.
VERRUCA PATCH:

Oh gosh...is it that bad?

You sneak another glimpse at the awful thing, wondering if it might not be as bad as you thought. The warts pop in and out as it speaks, like bubbles on the surface of a rancid pond.

Yeah, it's that bad.
FERN:

Sorry, I just...

VERRUCA PATCH:

It's okay, I'm used to it.

...Go ahead, I've heard 'em all. "How's the weather down there?" "Hey short stuff." Half pint, fun-size...I was malnourished, okay?! Why do you think I went bald at my age?! Laugh it up, gigantor!

FERN:

Er, no, you look, uh, fine? I...I gotta go.
