At bedtime, Mom reads Trek "The Wonderful Wizard of Oz". Trek drifts off and ends up in "The Land of Dinoz" where he meets new pals the Scare-Troodon (Penelope), the Tin-Dromaeosaurus (Bobby) and the Cowardly Stygimoloch (Hannah). Together, they all head off to see the wizard and save him some wicked dinosaur skeletons.
