.. Photo of a monster

No! You want to protect him. You need to make up a monster.

You could fake Bigfoot. Go find some props. ( There's props in the dorms. )

Now wear the monster prop and take a photo.

Kids... Use the kids. They can act as the monster.

In some place where no-one sees you. ( Take the photo in the forest. )

Go to the forest. Use the props on the kids. Use the camera to take the photo.

Barry and Larry will appreciate the photo, for sure.
