Release Date: October 28, 2025
Hosts: Mindy Thomas & Guy Raz
Featured Characters: Dennis, Reggie, Granny G, Tommy Fingerling

Episode Overview

Day 2 of Creepy Crawly Week turns the spotlight on some of the “grossest” and most fascinating insects and parasites in the natural world. Mindy and Guy Raz, joined by Dennis, Reggie, Granny G, and Tommy, explore the bizarre real-life tale of the lancet liver fluke—a parasite that turns ants into ‘zombies’ to complete its wild life cycle. The episode is told in a fun, storytime format with plenty of gross-out humor and dramatic performances, all rooted in actual scientific research to help kids and their grown-ups marvel at how strange and innovative nature can be.

Key Discussion Points and Insights

1. Launching Creepy Crawly Week (01:26–03:41)

• Dennis is in charge of Mindy’s pet cockroach, Smokey McDougal, and is NOT thrilled to be spending so much time with bugs.
• Ongoing theme: Overcoming the “ick” factor to discover the wonders of creepy crawlies.

2. Spooky (and Scientific!) Stories (05:05–06:20)

• The group tries to share “spooky stories,” mostly silly until Mindy starts a science-based scary story.
• Transition: Mindy announces she has a “spooky scientific story” from the journal Behavioral Ecology about the lancet liver fluke.

“Well, I did just read a spooky scientific study in the journal Behavioral Ecology.”
— Mindy (06:02)

3. What is a Parasite? (06:36–07:51)

• Explaining terms: Mindy and friends break down what a parasite is using silly analogies, making the concept understandable for kids.

“A parasite is like a little thief.”
— Mindy (07:14)

• Dennis comically explains a parasite as “someone who comes to your house, eats all your food, steals your friends, and crosses your name off your birthday card.” (07:20-07:42)

4. The Lancet Liver Fluke’s Life Cycle (08:05–21:29)

The Ant Eats Snail Mucus (08:05–09:32)

• The story begins with an ant that finds and eats a glob of snail mucus, unknowingly ingesting thousands of liver fluke larvae.
• “Snail mucus sure is tasty. I wonder what the secret ingredient is?”
  — Ant (09:02)

The Fluke’s First Problem: No Liver in Ants (09:32–10:08)

• Baby liver flukes realize: ants don’t have a liver. They need to get inside an animal that does—a cow.

Hijacking the Ant’s Brain (11:39–13:31)

• The flukes send one of their own to the ant’s brain. Via “mind control,” the fluke manipulates the ant to act abnormally, increasing its chances of being eaten by a cow.

“Now, the only way to get this ant eaten by the cow would be for the liver fluke to climb up, up, up into the ant’s brain.”
— Mindy (11:39)

• Silliness: “Napster, I’m in!”—the fluke pretends to hack the ant’s brain. (12:45-12:48)
• The ant climbs a blade of grass and stays there—perfect snacking spot for a grazing cow.

Inside the Cow – Surviving Stomach Acid (14:50–16:13)

• Cows eat the infected ant; the flukes huddle together in a hard-shelled capsule to survive stomach acid until reaching the liver.

“They have this unique ability to form a hard-shelled protective capsule around themselves.”
— Mindy (15:52)

Sacrifices and Transformation (16:23–17:30)

• The heroic fluke who controlled the ant’s brain does not survive, sacrificing itself for the rest.
• Dramatic farewell: “Fare thee well, my lovely larval liver flukes.” (17:19)

Completion and Reproduction (18:47–19:16)

• Once in the liver, the flukes feed, mature, and lay eggs.
• Eggs exit via cow dung, ready to restart the life cycle.

Completing the Circle (19:20–21:41)

• The fluke eggs await a snail; snails eat the poop and become new hosts for baby flukes.

“A slime ball filled with baby larval liver flukes oozes out of the snail and is left on the ground just waiting to be eaten by an ant.”
— Mindy (21:29)

5. Reactions and Takeaways (22:04–23:30)

• Everyone shares which part of the story they found most fascinating/gross.
• Dennis is shocked to learn the tale is actually true science.

“I didn’t come up with any of that story on my own. These were scientific observations by researchers at the University of Copenhagen in Denmark.”
— Mindy (23:04)

• Key Message:
  “Sometimes science can uncover truths about our world that seem like spooky stories. And sometimes science is stranger than anything we could possibly make up ourselves.”
  — Mindy & Guy Raz (23:18–23:24)

Notable Quotes & Memorable Moments

• “This story is getting scientific, Guy Raz!” (15:34)
• “What can I say, Guy Raz? Science is bonkerballs.” (16:18)
• Liver fluke (dramatically): “My work here is done. I made the treacherous climb… took control of that ant’s brain and turned it into a zombie… and found you a liver to call home.” (16:41–17:19)
• Granny G: “That is not how I like my eggs.” (19:34)
