For my son's 5th birthday we celebrated with a Dinosaur Dig! Each kid got a dig site access pass when they arrived, and a safari hat. They dug for dinosaur bones in containers of sand and used brushes and tools to "excavate" the fossils. There was a giant Dinosaur colouring poster, and a Dino egg hunt!
