Young cats Ollie and Moon have an appetite for adventure. While they're best friends, they have different personality types. Moon is the more adventurous of the two, and Ollie tends to err on the side of caution more often than not. When the cheery Moon gets an idea, she often drags Ollie with her on an expedition around the world. Along the way, they teach viewers about the benefits of unlikely friendships and global citizenship. The live-action/animated series is based on a series of books by Emmy-winning artist Diane Kredensor ("Pinky & the Brain").
