School is about to start, come and help students clean up the messy school, including the observatory, playground, bathroom, classroom and chemistry laboratory. These places are very important to the school, so you need to do your best to make the school shine again. In addition, the school bus that takes students home every day is also very dirty, so you need to help teachers scrub the school bus in the playground and make some decorations for the school bus, including changing tires and spraying paint on the body. You can choose your favorite pattern and color, are you ready?
