The insect world is full of sneaky disguises, secret signals, and copycat creatures… In this wild episode of Wow in the World, Mindy and Guy Raz uncover one of the strangest examples of mimicry in insects ever discovered, and the even stranger example of insect mimicry from Dennis's childhood! From caterpillars pretending to be baby ants to baby dolls pretending to be Dennises… mimicry has never been so bizarre!

Dennis and Baby Dennis are in the middle of a full-blown mustached meltdown after Baby Dennis mysteriously locks Dennis out of his own home. Or, as Gramma G-Force keeps reminding everyone… his mother's home. As Dennis pounds on the door demanding to be let back inside, Baby Dennis insists that only the “real Dennis” knows the secret code. Uh oh.

What starts as a neighborhood argument quickly turns into a science mystery involving possible identity theft, ant colonies, sneaky caterpillars, and one very dramatic puppet! In this episode, kids and families can dive deep into the fascinating world of gossamer-winged butterfly caterpillars—tiny tricksters that use insect mimicry to survive by fooling entire ant colonies into believing they're part of the family. These caterpillars don't look like ants at all, but somehow they convince ants to carry them into their nests, feed them, protect them, and sometimes even prioritize them over their own babies! How? By harnessing the art of insect mimicry.

Grab your bug spray and zip up your mosquito-proof jumpsuit, because this episode of Wow in the World is buzzing with science, chaos, and one very complicated game of “Mosquito Tag!” illustrating why mosquitoes bite certain people! Perfect for kids and listening with the whole family. On a hot summer evening, Mindy, Guy Raz and the crew gather outside for what should have been a simple game of tag…until a swarm of mosquitoes crashes the party and turns the whole thing into a deep dive into the weird and wonderful world of mosquitoes and why they choose to make a meal out of you!

Why do mosquitoes seem obsessed with biting some people while completely ignoring others? Are all mosquitoes blood-sucking pests? And why does Thomas Fingerling somehow attract every mosquito within a five-mile radius? Along the way, Mindy and Guy Raz reveal the surprising truth about mosquito biology! And the science gets even wilder when the crew dives into a real-life experiment inspired by researchers at Georgia Tech. These scientists wanted to understand exactly how mosquitoes track down humans, so they created a special mosquito-testing room filled with clues mosquitoes love… as it turns out, mosquitoes don't just randomly fly around looking for snacks—they combine multiple clues to zero in on their targets like tiny flying detectives!

Through hilarious roleplay, disastrous experiments, and Dennis's increasingly dangerous game rules, the crew discovers how mosquitoes use sensory clues to decide who gets bitten next. This episode for kids and families also explores how scientists hope this research could lead to better mosquito traps and new ways to stop the spread of dangerous mosquito-borne diseases around the world.

It's an episode crawling with outrageous comedy, gross mosquito facts, pretend blood-sucking, and enough buzzing sound effects to make you itch just listening!

In this tail-wagging, brain-boosting, and totally paw-some episode of Wow in the World, Mindy, Guy Raz, and the WOW crew dive into the surprising science of label learning! At the Dog Vocab World Championship, label learning takes center stage as some of the smartest pups on the planet show off their incredible memories. And as Mindy and Guy discover, label learning might help explain how dog vocabulary works and why dog vocabulary in certain dogs can be way more impressive than you'd ever expect!

When Mindy and Guy Raz arrive at a giant stadium to commentate the annual Dog Vocab World Championship, Mindy is mostly focused on one thing: finding a snack. Unfortunately for her, she ends up in the dog toy line instead of concessions and barely has time to figure out what's happening before she and Guy are rushed on air. Once the lights go up and the crowd starts barking, cheering, and howling, Mindy realizes this is no ordinary dog show. This is a high-stakes battle of memory, focus, and fetch.

The competitors? A trio of elite canine superstars: the polished Professor Lex, the rebellious fan-favorite Noodle, and the reigning champion Banjo. One by one, the dogs are asked to retrieve specific toys from a big pile on stage, including avocado, monkey, racecar, airplane, and more. To win, each dog must remember which word belongs to which toy and fetch the correct one without making a mistake. It's like a spelling bee, a memory game, and a sporting event all rolled into one very fluffy package.

But amid all the excitement, Mindy and Guy uncover the real WOW: a fascinating new scientific study from researchers in Budapest suggests that some dogs may not only learn words through direct teaching, but also by simply overhearing humans talk to one another. That means a dog might be able to learn the name of a toy even when no one is talking to the dog directly! In the study, researchers worked with special dogs that already knew lots of toy names. Then, instead of repeatedly teaching a new word face-to-face, the dog's owner and another person casually talked about the toy together while the dog watched and listened. Later, many of the dogs were able to fetch the correct toy, proving they had learned the word just by overhearing it.

Scientists call this process label learning: understanding that a word belongs to a specific object. It's something human babies do too, by listening to the people around them talk. And it turns out some dogs, especially highly attentive breeds like Border Collies, may be able to do something surprisingly similar. That makes these pups true outliers in the animal kingdom, with some dogs able to recognize hundreds, and in rare cases even over a thousand, words.

With live commentary, dramatic toy fetches, barks from the crowd, and an unforgettable championship showdown, this episode is packed with laughs, suspense, and an incredible look at how dogs learn.

In this high-speed episode of Wow in the World, Mindy and Guy Raz turbocharge an ordinary day… It's the 25th-Annual DIY Homemade Go-Kart Derby! But in classic Mindy fashion, she isn't showing up with just any homemade kart—she's built a cutting-edge Formula 1-style race car! As it turns out, Formula 1 racing is basically “one giant science fair,” powered by teams of scientists working to design the fastest cars possible!

Of course, getting to the race is no simple task. Instead of driving, Mindy insists on preserving the precious engine by enlisting the sleigh cats' help to pull the car. At the track, they meet their driver– a familiar and unlikely face– and prepare for the big race. As the countdown begins, excitement builds, blending science, silliness, and speed into a wildly entertaining race-day finale!

Packed with humor, wild antics, and fascinating STEM concepts, this episode shows how science fuels everything from backyard projects to the fastest cars on Earth.
