When the Sub-Idolcomp sent Dr. Diggins back in time to the Jurassic Period, he traveled across Vivosaur Island to get to the crashed space ship on Secret Island. Along the way, he managed to find time to carve his misadventures into stone Slablets, which he left scattered inside the Dinaurian Spaceship. In the order that it happened he lost his Sandal on the trip, was almost eaten by a Tyrannosaurus (saved only by his mint soap), stumbled across a Stegosaurus and her baby, and rode a Plesiosaur half way across a lake, just to be flung the rest of the way.
