Crawly

Crawly likes to eat your fingernail clippings.

That's why he doesn't talk.

They become his teeth,

First Diary
Free flowing tentacle-things.

Second Diary
Are you in the party, yet

Third Diary
Stop eating fingernails.

Fourth Diary
It's disgusting.

Fifth Diary
I wanna cry.

A Legend of False Hope

Sixth Diary
Maybe you'll evolve into a dang fingernail, Crawly!
