Yellow House

We're in a yellow house. This house is a 4-room house. Each room is beautiful apart. You ask why.? Because the rooms are colorful and warm. But we have a problem. Some of the stuff in the house has disappeared. We need to find these items that are important to the landlord and put them in their places. Another important matter was that 7 coins were lost in the house. We have to find them all at once. We wish everybody a lot of fun.
