The rug and sofa

Approaching the sofa first, it seemed luxurious and comfortable. Soft, cream-colored pillows sat atop the fancy piece of furniture, just begging Kasha to lay down and rest. That was tempting considering she'd spent the past few hours diving through a dungeon. But she also had the mental image of a key falling out of someone's pocket into the cushions. Maybe it would be worth it to rummage between the cushions?

There was also the rug, seemingly an oval shape, part of it was hidden beneath the sofa. It was vibrant red in color, and was soft beneath Kasha's feet. Maybe the key was hidden beneath it?
