From the New York Times bestselling illustrator of Battle Bunny comes a laugh-out-loud story of a little sponge dinosaur that keeps growing...and growing...and growing....
Cole is very excited about his new Dino-Gro toy. He can't wait for it to reach its full size! But when Dino-Gro becomes much larger than intended, Cole goes so far as to put Dino-Gro on a liquid-free diet and an exercise regimen, which don't seem to make a difference! As Dino-Gro becomes so big that he can't fit in the house, Cole learns that growing up and getting bigger can have advantages too, even if you're not a dinosaur.
For fans of Tiny T. Rex and We Don't Eat Our Classmates, this sweet and hilarious read-aloud is fun for kids to learn the importance of growing up big and strong.
