From singing the Happy Birthday song to eating (or smashing!) a special cake, the Cat in the Hat, Thing One, and Thing Two throw little readers a first birthday party they will be sure to love.

Inspired by Lala Watkins’ childhood and Dr. Seuss’s sketches, including one of a worm-like creature, Hello, Sun! is a joyful Beginner Book about how Norbit the worm and his friends spend a day playing with the sun.

“The sketch with the eyes reminded me of shadows, which made me think of hide-and-seek. I remember on long car rides as a child, I’d stare out the window to see the sun following us. I’d play hide-and-seek with it, wondering where it hid as we passed trees and then spotting it again.” —Lala Watkins
