We are in a wooden house in the middle of a forest. This house has 4 bedrooms. When the house is made of wood, other floorings are naturally made of wood. But the butterflies almost invaded these rooms. Butterflies emerge from every corner of the rooms. Our task is to find all the butterflies. However, our even more priority task is to find 2 differences between the pictures given in a row. Again we will find a total of 10 differences. Since the bedrooms are similar to each other, they can show similarity in the pictures. We have the right to get 3 tips and we need to make good use of the time given.
