The skulls love this. They both nuzzle up against Chara's hands, their yips turning more and more affectionate.

"Greetings," Sans repeats, albeit somewhat slowly. He's heard the word before, but it doesn't really roll off the figurative tongue. He pulls himself out of the blanket and sits up. His legs cross and he holds at his ankles. Slowly, he sways back and forth.

"I like... I like your fur. Why'sit all up there?"

He points to Chara's hair. One of the blasters floats up higher and sniffs it. He's met a decent variety of monsters in his whole three years of being alive, but most monsters with fur usually had it all over. Then again, Sans has only just barely grasped the concept of skin and hair. Maybe they shaved it? Now he's thinking about Mr. Dreemur with no fur. Maybe he's a skeleton underneath?

"Do you have bones?"
