Printed entirely in green ink, these fun STEM-filled books are perfect for InvestiGators fans.

Croc and Gator could not be more different, but the one thing they have in common is the love of their swamp. And now they are old enough to train as junior Swamp Rangers! They can't wait to learn about all the swamp's plants and animals, and how to protect them.

When outgoing Gator and reclusive Croc are paired up, neither is sure about the other. But it turns out that their differences help them ace their tests and reward them training certificates to become the best Swamp Rangers!

This great buddy series pairs two animals that kids LOVE. In their challenge to become junior rangers, Croc and Gator will need to be courageous and brave little reptiles, as they explore their swamp and prepare to protect everyone in community.

With each story, readers will train alongside Croc and Gator, as they gain more experience and get badges along the way. The books will have back matter to support the theme of each story.
