In a room with no light, Yuri has a magical lantern that only illuminates things that are alive. He's looking for his friend Kioni, who's hiding somewhere in the room. There are a few potted plants scattered around and a cat named Miso sleeping quietly in the corner. Without making a sound or physically searching the room, how can Yuri use his lantern to find Kioni?

Provide a very brief response.
Yuri turns on his magical lantern in the dark room. The lantern illuminates the potted plants and Miso the cat, as they are alive, but inanimate objects remain unseen in the darkness. Since Kioni is alive, when Yuri scans the room with his lantern, the area where Kioni is hiding will start glowing, revealing Kioni's location. The light from the lantern is the key, as it selectively reveals only living beings. Yuri can easily locate Kioni by observing where the new source of illumination appears in the room, apart from the plants and Miso.
