Rick moved to nearby sit. Anyway if he, or she, wanted to make Emily human back, she had to find where the tree is and take its picture at there. She put down the picture to take a closer look, with the camera next to it... and unwillingly another picture of the picture of the tree made!
FLASH
The camera was on 'Blend In with the Environment' setting, but it considered the view of an oak tree at a pasture as a background, and the whole mall behind it as a subject. It was going to change everything and everyone in the mall to something else fit with the tree.
Because of how the subjects were huge, it taked a little time for the camera to change them all. Meanwhile Rick could see all in her sight changing... but not to stop it as she was in frozen state.
She saw a kid and his parents becoming an oak tree and two mushrooms on it. A nerd at the bookstore became a fish in the pond, which was the books in there. A family of a baby and twin girls with their parents changed into an alpha wolf and his pack. Some people behind the crowd were seen as they got taller as a tree between swarm of ants.
Rick herself was also a part of transforming the entire mall into a forest. Her size shrinked, skins were green and wet... Rick became a frog.
She(or He? We still don't know if Rick is a female frog or not...) was swimming in yhe pond where was fill with books a minute ago. Rick jumped on the lotus leaf that was a girl in the bookstore with Rick, because the camera on it. Was Rick able to use it?
