Go to: Cul de Sac by Richard Thompson
Petey's been reading some pretty old books or watching Ray Harryhausen movies, because he should be too young to remember that era.
Update: Dinosaurs just got insufferably cuter. Deal with it!
Come to think of it, Petey reminds me of Michael Crichton complaining about those weak-minded, liberal scientists through his mouthpiece Ian Malcolm in The Lost World:
"Dinosaurs were now seen as caring creatures, living in groups, raising their little babies. They were good animals, even cute animals... And that new sappy view produced people ... who were reluctant to look at the other side of the coin, the other face of life."
