This is the last episode of Season 4, but stay tuned for our special summer lineup! We’ll be back for Season 5 in fall 2019.

Why are butterflies so colorful? That’s what Zed, from The Petit Punk Podcast, wants to know. So we went on a family podcast field trip to the Museum of Natural History in Paris, where we met Zed, his mom Dana, and a butterfly scientist named Marianne Elias. Come with us as we visit the museum’s private “butterfly library,” and find out why some butterflies are toxic! Plus, we’ll learn why Marianne climbs trees when she’s not in her office. Also, a special original butterfly song from Dana & The Petit Punks!
