.. Cellar

Did you notice what the monster did when Tove lit the light?

Yup. It will break the floor above when the area is lit. You can try with the other lamp.

There's a flashlight on the box right from the stairs.

You find the first battery just by seeking for it. ( Open the lower cupboard door to find a battery. )

Where do you would get another? Something is using a battery right now.

Open the robot.

Great! Put them into the flashlight and lure the monster.

Use the flashlight on the red sled. Use the sled to escape.
