From the best-selling creators of Unicorn Day comes a dino-mite celebration as all dinosaurs, big and small, celebrate Dinosaur Day!

Hooray! Hooray!

It's Dino Day!

The dinosaurs are on their way!

The ground starts shaking-

Here they come!

Thumpa-bumpa,

rum-tum-tum!

Dino Day is finally here, and it’s dino-mite. 

On Dinosaur Day, dinosaurs love to stomp and chomp. But they like silly singing, rowdy swimming, and yummy desserts too. All this fun makes the baby dinos want to join, but something unexpected pops up. Will the dinos accept this new addition to keep Dino Day going?
