Amy tried to hit the walls so she had more room to grow. She continued to grow but she still didn't have the strength to break them. Then her head went through the second ceiling and into the final level. If she got any bigger she would go through the roof.
"Why won't I stop I'm big enough?" asked Amy.
To her horror she was still growing. After a few seconds her head hit the roof. She started to bang it with her hands. But this time she had the strength needed to break it.
She grew right out of the hole in the roof she had made. A crowd had gathered around the building.
"Er hi," said Amy.

What does the crowd do?
