Set the scene for your new dino friend. Toysmith's dinosaur mini worlds come in a yellow case shaped like a backpack. On the front of the backpack is a transparent lid showcasing a tiny dinosaur figurine. The lid can be opened to replace the dino and its background. Inside the backpack are additional background settings to replace in the front lid, two other dino figurines in assorted colors and 5 other pieces to set the dinosaur's world, such as trees and dino eggs.
