The duckbill dinosaurs live across the river from the T-Rex’s. The duckbills are peaceful plant-eaters. The T’s are scary meat-eaters. When a duckbill egg hatches in the T’s nest, both the new baby and the T-Rex family must try very hard to get along. But the little dinosaur, nicknamed Drip by his new family, soon proves he’s not such a drip after all—in fact, he’s a real hero!
