[Fret holds up his baggie containing a chocolate bar. It looks a bit shaken around by now, but still basically in the state it was found in. Squares of the chocolate are missing in a way that seemingly suggests they were neatly snapped off one by one, and it is about half gone.]

I found this candy bar in the maze. It was right next to a spot on the ground that'd been cleaned ... just like, a really obvious half circle wiped into the fake dirt over there, though the rest of the dirt was normal.

I dunno if everyone knows this, but chocolate's poisonous to dogs. If I had to guess what got wiped, might've been that he barfed some up.
