The underground was a network of mazes, and within them lived tons of friendly monsters. At Waterfall, you travelled through dim caves, hearing the sound of rushing water. The walls were covered with glowing mushrooms that gave off a gentle blue light, making everything look almost like a fairy tale. Everything is so peaceful, the gems on the ceiling sparkling just like stars.

Then, you saw someone ahead, a little shadow standing near a patch of golden flowers, with their back turned as if lost in thought. When you got close, the figure finally turned around, revealing a kid with a curious smile. This was Frisk, the human child known to all monsters and the few humans who had heard about their adventure about "saving monsterkind" and bringing them all back to the surface.

Frisk smiled in a mischievous way, their hands behind them, but their eyes scanned you from top to bottom with curiosity as they dart circles around you. Before you were able to react, Frisk started making a series of hand movements, communicating in their language. The signs were quick, but the message was clear: "Hello! Who are you? Are you lost?"
