You are looking at a warning to all cowilians

It has been discovered that COW has gained the attention of the notorious "grues".
(for those who have no idea what a grue is, they are mean and thats all you need to know)
[well and the fact that they like really dark places, like caves or attics or basements etc.]

Chaotic Bob can only confirm the presence of a single grue.

"Geez, I was just wandering the bowels of the lake and came upon a nice little cave. So I figured 'Hey, I like cave 'sploring so what the hey?'. Next thing I know I hear a little voice in my head say 'You are likely to be eaten by a grue', so I naturally ignored it completly. Until I was being stuffed into the maw of some horrid beast. I naturally did what any upstanding cowilian would do. I screamed for my mommy and used my patented C.C. Run Home to Mother device and barely got away."

Snoopy (yes the little dog from Peanuts) wants Charlie Brown to bring him his dinner. He's currently in the bowels of a Eurg. (eurgs are bad)
