Rulle is a little robot with soft lights that glow blue and warm. He hums softly: Hum, hum. Blip, bloop. Rulle lives in Maja's room, and it's evening.

Maja yawns, and so does Teddy. Rulle rolls slowly, his wheels making a quiet Click, click sound. He helps out by putting blocks in a box: One block. Two blocks. Three blocks. Everything becomes calm.

Rulle presses a button, and it glows faintly. The room becomes soft and kind as small stars dance on the wall. Rulle shows the moon with a little lamp. Maja points and smiles, and Rulle smiles back with his lights.

Rulle sings his robot song: Blip, bloop, good night, good night. Maja and Teddy listen as hearts become calm. Breathe in. Breathe out. Peace and quiet.

Rulle says good night to things: Good night, book. Good night, car. Good night, clock. Tick, tock. Good night, computer. Rest now. Everyone rests, and everyone is safe.

Rulle goes into sleep mode. His lights become like stardust, and his Hum, hum becomes quiet. Maja hugs Teddy and whispers, "Good night, Rulle." Rulle blinks a little light: Blip. Good night.
