How about if one day, there is a group of fairies ( male and female ) who live in a tiny village in a forrest. One day, there is a fairy out gathering food for her clan. All of a sudden she sees a giant face at her from the sky over the forrest. She runs back to her people to tell them about what she saw. But nobody believes him or her. Until one day, more than one fairy is outside and they both see the giant face appears above them in the sky. The giant tells them that all along there village is really inside a snow globe ( without the snow ) The faeries don't believe the giant at first. The giant taps on the sky, it is glass. The giant tells the two faeries that he is a scientist in a lab and has been studying them for a long time. OR maybe the giant could offer to shrink himself down and come inside the globe. The faeries aren't too sure about letting an outsider in. They ( the faeries ) reluctantly agree. The giant scientist shrinks himself down and enters there world. Maybe the giant scientist could befriend one of the faeries, and she could go with him outside the globe, while the tiny scientist is shrunken, he could grow back to a giant when they are outside the globe in the lab. OR maybe inside the globe while the scientist is shrunk. The potion that he drank to make him shrink, begins to wear off all of a sudden, without warning and he could grow inside the globe breaking through the globe. ( Which could make for a very cool growing scene
) The clan of faeries could wonder if they could trust him when they see him grow. The faeries could run inside there homes. The giant could pick up all the tiny homes in his huge hands to protect them from being crushed by himself, as he grows through the glass.
