This week Charlie and Kirby are playing the role of wildlife sheriffs - investigating invasive species crooks that are wreaking havoc on the environment! After a little research, it's off to the Everglades to catch some caimans with the help of a local scientist. There they'll learn how species invade non-native habits and why it's important to monitor them to keep ecosystems balanced.
