Little Dinosaur roars his way through a number of daily challenges, but he cannot seem to defeat bedtime.

Dinosaur is going to one of his favorite places, the library, and on the way he encounters a series of animals, including a cow, baby chicks, a turtle, and an owl, and shares his roars with each.

Fearless Dinosaur takes on new challenges as he starts preschool, from meeting new friends to pasting glitter and googly eyes, but one task requires assistance from everyone.
