One day, when Winnie and Wilbur are flying over the museum, they see a crowd of people gathered around a huge dinosaur skeleton in the courtyard. It's a Triceratops and there's a competition to draw or make a model of what the dinosaur would have looked like when it was alive. Winnie is really keen to take part! But she just isn't sure what the skeleton might have looked like so she decides the only way to find out is to magic herself and her (not-so-willing) cat Wilbur back into the time of the dinosaurs! Once they arrive in the prehistoric swamp, Winnie and Wilbur hide behind a tree and it's not long before they spot a Triceratops munching the greenery. Pencils and sketchbook in hand, Winnie just can't capture the dinosaur on paper so instead she jumps onto his back and Winnie, Wilbur, and a rather surprised Triceratops crash into the museum courtyard just as the prize is about to be presented by Professor Perkins. The Triceratops is even more surprised when he is given the prize! Then Winnie and Wilbur take him home and it's time for one last magic-wand moment so that Winnie's prehistoric friend can really fit in to his new surroundings.
