How dare you draw graffiti in my area?!

As soon as Cup Bros got their airplanes, they were so excited that they can fly by airplanes everywhere. 
They realized the planes can make vapor trails and started to blow long cloud out on the sky. Finally, the picture was completed!
It's perfect!!  
However, the sky was the most important area of Hilda Berg. She didn't feel so good because she looked like they were ruining her area.
From now, you can imagine what she would do.
