Aiden is an active three -year- old who loves dinosaurs and everything about them. Come join him as he goes on an adventure to the local museum where it is transformed into a magical place during the time when dinosaurs roamed the earth. There he meets some of his beloved dinosaurs, from the ferocious T. Rex to the spiny stegosaurus. He gets to dig for dinosaur bones and makes a dinosaur necklace. He paints a picture of his favorite dinosaur, the T. Rex.

At first, he's afraid to go into the museum. Loud sounds can be heard coming from inside. His dad reassures him that everything will be all right. Soon he begins to enjoy the games and activities. Outside the museum gets to bounce in a bounce house, slide down a giant dinosaur slide, and ride the roaring dinosaur train.
