What if hundreds of your toy dinosaurs mysteriously came to life...? Iggy Risner is your typical wise-cracking twelve year old. When his younger brother, Oz, wakes him in the middle of the night claiming he heard a monster in the attic, Iggy takes him upstairs to prove him wrong. But instead of a flesh-eating beast, they discover hundreds of their toy plastic dinosaurs that have mysteriously come to life. When the dinos escape the attic and start terrorizing young kids in the neighborhood, and trampling flower beds, somehow Iggy, Oz, and their friends must catch the plastic dinos of doom before the damage escalates. But what do you do when your parent's doubt your story, and a group of clueless neighborhood bullies stand in the way? For Iggy & Oz- Catching the little beast may prove to be easier said, than done.
