Super Saurus has a new superhero mission: He must learn how to welcome a new sibling into the family!

When Arnold's parents bring an egg home and tell him he's going to be an older brother, Arnold is not convinced. Arnold knows the egg could be anything. . . maybe even an EGG OF DOOM!

If a vampire-saurus flies out of the egg, Super Saurus will be ready! If a planet-crushing robot stomps out of the egg, Super Saurus will be ready! If Maud the Marauder jumps out of the egg, Super Saurus will be ready! But what happens if the Egg of Doom turns out to be Arnold's new little brother or sister?

With the same wit, humor, and charm that shines in Super Saurus Saves Kindergarten, this super sequel will be sure to captivate new and old readers alike.
