Trampoline with a Trap Door?

Occurred on May 5, 2019 / Bellevue, Ohio, USA

Info from Licensor: "My daughter was waiting for her friend to get ready and decided, 'I'm going to try a full on that trampoline quick.' She is an all-star gymnast and cheerleader. I tried to quickly video her doing it in jeans. I was confused when I didn't see her on the trampoline and saw her laying under it. I was laughing too hard to even get out and check on her."
