Ignatius is an adult compsognathus, one of the smallest dinosaurs there is (under 3 kg).
In complete contrast to his small size, Iggy has a deep, booming voice and acts like a tough guy, strutting about like he owns the place – when the coast is clear. But at the first sign of danger, Iggy zips off to hide. And when running off, he’s in a class of his own: compsognathuses are very fast dinos indeed. Bill wishes he had Iggy’s speed!
Safe hiding in the crack of a rock, Ignatius will continue his tough guy act, projecting his voice to antagonize predators…so that it seems like someone else is calling them out. He finds this prank hysterical. But it has gotten our four friends in plenty deep trouble at times!
