Sans looks at Greg, watching what he's doing. Flashlight. Huh, maybe not a bad idea after all. He follows the beam of it out onto the grass, where the shadows lay, and in some spots you can still see the green and the texture of grass, whereas other places are pure black and oddly slick, as if they were great wet blankets strewn across the ground.

Kind of gross?

"Nice," Sans rumbles, which is probably a really weird thing to hear a huge skeleton dog say about your flashlight. He unwinds his tail so that it's less of a barrier to Greg's movement, and instead leaves it to sit wider out - more like a fence that Greg could hop over than something forcing him to stay inside. "Thanks. Hold that."

Sans starts to slink forward, approaching the edge of one of the 'blankets' that he can see outlined against the grass. Moving forward makes it necessary to retract his tail from protection duty, but he's hoping that Greg will keep his head on straight during this.

Sans leaps forward all at once, snatching at the edge of the darkness with his fangs, and digging into it as if some kind of thick fabric. He rears back and pulls, and the front section of it peels off of the ground with the softest sound of a screech, like a single insect screaming. He digs his claws into the base and stars jerking it around in a very dog-like motion, until a section of it tears off, which he proceeds to... eat?

At the very least, he get it in his mouth, which proceeds to light up with cyan flames and burn it into nothing. The other half of the blanket wriggles beneath his claws.

"Gross."
