We are in a house designed entirely for young people. Everything in this house is very sporty and spacious. For example, you can play table tennis in the attic, play sports in the basement, and watch TV in the living room. But we have a small problem. Although the reason is not clear, the house is very messy. Young people like to mess around. It is up to us to gather this mess. We need to find the hidden objects immediately and put them in place.
