It's the story of a pair of young pterosaur twins who fight loudly and incessantly all day long.
One day their raucous shouting over who will get to eat a fish attracts a variety of other dinosaurs, who all offer up ways to solve the argument - but to no avail. This in turn leads to an intervention by Tyrannosaurus Rex.
Who promptly eats them.
As you can imagine, it's rapidly become a favorite among the adults in the household.
