Coral Reef Room,Amazing Wonders Aviation .Very Simple. Find an old trunk, stuff it with brown paper, top with little girl's jewelry and gold coins and you have a treasure chest! Background, coral reef is from Party City,$7.99, topped with blue paper from Ed.Wonderland, reefs can be made from cardboard, but we had foam board from last year's VBS and just paint! We placed a tan sheet on floor for sand. Kids loved it!
