Real nature science, with songs and zero shame about poop.

The gist

Terrestrials turns real field science into kid-friendly stories: Arctic squirrels that go eight months without pooping, loons that can stay under for minutes at a time, chinstrap penguins making the case for naps. Original songs, gross-out questions answered in earnest and a listener Q&A called The Badgers keep the silliness tied to the facts.

About Terrestrials

Terrestrials is a family-friendly nature show hosted by Lulu Miller, built on the stranger facts of animal, plant and microbial life. Take Arctic squirrels. Out in the snow, Kelly describes the burrows beneath, which the squirrels line with moss, lichen and caribou fur before each one curls up alone for winter. Once under, they stop eating, stop dreaming and go eight months without pooping, and scientists in the 1960s played catch with them without waking a single one. That mix of solid fact and delighted disbelief is what the show does best. The subject range is wide. Titles run from 'The Greeting: Yo-Yo Ma's Humpback Whale Experiment' and 'The Red-Eyed Mascot: Loon Resilience in Minnesota' to 'The Snoozer: Penguin Slackerzzz Rule' and 'The Spellbook: Ancient Recipes for Animals', each fronted by a short nickname. Inside, the science goes further than the nicknames let on. At the bottom of a lake hole, microbes bob toward the light like a lava lamp, a habit linked to the ancient shift from six-hour days to twenty-four. A chinstrap penguin takes the microphone to defend napping as 'adaptive inactivity.' In the Yo-Yo Ma episode, a storyteller introduces Kanaloa, the Hawaiian deity who holds the oceans and their creatures, and adds that only about five percent of the sea has been explored. Humor does a lot of the work. A listener named Mo asks whether loons fart. Walter, who helps capture and band loons, admits he has never checked, then writes back after looking into it to report that they do not. The reply earns a pun about breaking wind. Listener questions also get their own closing stretch, The Badgers, where they go straight to the experts, cued by a chorus counting off 'me too, me three, me four.' Music is everywhere. Alan Goffinski, credited as The Songbud, is behind the original songs, which are also collected on Spotify. One closer insists 'you gotta yum your yuck,' and another dissolves into a chant about being a penguin at the big poopy club. The tone can soften as well: the Yo-Yo Ma episode ends on a quiet dedication. For classrooms, the team has built handouts, activities and discussion prompts with PBS Learning Media for grades K-8, available at radiolabforkids.org. A natural first stop is 'The Fuzzy Ruckus', the lichen episode Lulu names among her favorites, featuring the storyteller Ash and the magnifying glass Ash carries on hikes to inspect mosses and lichens. Episodes sign off with a promise to return in a couple spins of this dirty old planet, though the planet is sometimes lumpy and, in the episode about holes, holy.

Made for: Suits a listener of any age who wants surprising, true animal facts delivered with songs and silliness, and who thinks a question like whether loons fart deserves a serious answer. It also fits a teacher looking for nature stories that come with classroom handouts and discussion prompts.

What sets it apart: Terrestrials builds its science into a performance: original songs, a penguin's speech in praise of naps, and puns about breaking wind. Its closing segment, The Badgers, then hands listener questions straight to the experts.

In their own words

Welcome, nature lovers, to the home of the Terrestrials podcast and family-friendly Radiolab episodes about nature. Every other week, host Lulu Miller will take you on a nature walk to encounter a plant or animal behaving in ways that will surprise you. Squirrels that can regrow their brains, octopuses that can outsmart their human captors, honeybees that can predict the future. You don’t have to be a kid to listen, just someone who likes to see the world anew.You’ll hear a range of nature stories on this podcast. Sometimes these will be brand new Terrestrials episodes, full of original songs (by “The Songbud” Alan Goffinski) that tell a fantastical-sounding story about nature that is 100% t…

Short reviews from the PlayNext desk, based on the episodes we processed.

The Greeting: Yo-Yo Ma's Humpback Whale ExperimentApr 9, 2026

A reflective whale episode connecting ocean mystery, Hawaiian cosmology, and a Yo-Yo Ma music project.

This single episode brings whales to the crossing point of music, ocean mystery, and Hawaiian cosmology. Lulu and Alan shape the sea through Kanaloa, presented as a Hawaiian deity tied to the ocean, its creatures, and a realm beyond ordinary knowing.

The Red-Eyed Mascot: Loon Resilience in MinnesotaMar 26, 2026

Loon anatomy gets funny, specific, and satisfyingly strange from lake surface to bathroom humor.

The Red-Eyed Mascot finds a lively shape for loon science, turning oddball questions into a grounded look at a bird made for water. White poop, underwater breath, solid bones, powerful legs, takeoffs, and flight all become ways to show how the body works as one design, not a…

The Snowball: Extreme Squirrels in the Arctic (Replay)Mar 12, 2026

A strange, funny winter dive into squirrels, hibernation, and the science beneath the snow.

Extreme cold opens onto a wonderfully odd look at squirrels living beneath the snow. They build careful burrows, pad them with mosses, lichens, and caribou fur, then disappear into an eight-month sleep without eating or defecating.

The Snoozer: Penguin Slackerzzz RuleFeb 26, 2026

A chinstrap penguin makes napping feel like smart survival science, with just enough silliness to keep it lively.

A chinstrap penguin turns rest into a surprisingly persuasive bit of survival science, making the case that what gets dismissed as laziness can also be adaptive inactivity.

The Portal: Groundhogs Lead Us Into an Underrealm of HOLESJan 29, 2026

A hole leads to microbes, ancient sunlight, and breathable air.

The episode treats holes as a way into hidden worlds, starting with ordinary sidewalk gaps and small close-up finds before landing at a lake-lit opening where purple and green microbes rise toward sunlight and sink as it darkens.

The Spellbook: Ancient Recipes for AnimalsJan 15, 2026

A messy, funny case for looking closely at what frightens, disgusts, or slips past notice.

Curiosity gets a little grimy in this single-episode review, following Francesco from the dangerous question of drinking snake venom into squirmier territory: maggots, pond water, and the busy life revealed by a microscope.

The Slowpoke: How Sloths Grow InvisibilityDec 18, 2025

A birthday-timed boat trip gives this tiny endangered sloth story an easy sense of wonder.

Terrestrials opens on a cleanly appealing quest: zoologist Lucy Cook wants to see Panama's endangered pygmy sloth, a creature described as among the rarest sloths on the planet and roughly loaf-sized.
