In this Postcard from Earth, Flip sends a letter home about one of the most mysterious human rituals she has encountered yet. While visiting a place called a "shoe store," Flip becomes convinced she's stumbled upon a temple devoted entirely to strange foot coverings. Why are humans so fascinated by shoes? Why are some shoes displayed like precious treasures? And why do the temple attendants kneel before visitors? What begins as a simple shopping trip quickly becomes another wonderfully confusing Earth mystery.

This hilarious alien correspondence is packed with laugh-out-loud observations and the delightfully upside-down perspective that only Flip & Mozi can deliver. As Flip and Mozi attempt to understand humanity's obsession with footwear, they discover that even the most ordinary Earth experiences can seem completely extraordinary through alien eyes.

Along the way, Flip and Mozi marvel at the many different kinds of shoes humans wear, puzzle over why some are treated with such importance, and debate whether socks deserve their own stores. Between Mozi's determination to own every pair of shoes in sight and Flip's increasingly exhausted explanations, this Earthling encounter is full of curiosity, comedy, and plenty of sole-searching. It's the kind of adventure that makes you see everyday life from a hilariously different perspective.

Flip & Mozi is the hit podcast from Tinkercast, the creators of Wow in the World, featuring original music from Grammy-nominated artists The Pop Ups. Each episode, aliens Flip and Mozi crash-land into a new animal encounter as they try to figure out what it means to be an earthling. From mammals to insects to sea creatures to reptiles, every curious creature they meet teaches them, and their listeners, something new about Earth and the important role animals play in our ecosystem. It's a nature and animal podcast for kids that keeps animal conservation in your family's conversations.
