Mama Rex and T are two dinosaurs living in the city. T, a young dinosaur, is just like any other kid--he stays up late, he messes up his room, he gets in trouble, and he loves his mom. And Mama Rex is just like any other single working mom--she drinks lots of coffee, she's always running late, and she loves T more than anything else in the whole world. Now T has to make a diorama about pigs for school. But T doesn't know what a diorama is, and T doesn't know anything about pigs! Mama Rex and T have one night to pull this project together--can Mama Rex save T from diorama disaster?
