Season 3

George and the Man with the Yellow Hat are having a blast on their research assignment in the Antarctic! Professor Wiseman has enlisted the pair to help find the nesting grounds of the Chinstrap penguins. Equipped with a video camera, two-way headsets, and a photo of the penguins, our two explorers set out in different directions. George meets a Chinstrap penguin, only to lose his camera to a pesky sea otter who swims away. The Man finds George, and they chase the sea otter by jumping ice floes...and discover too late that a blizzard is approaching! George and the Man find refuge in a cave. When the blizzard passes, they emerge on the other side of the island in the middle of the Chinstrap penguins' nesting ground! Mission accomplished!

George and Bill run out of carrots while feeding the rabbits. When Bill pulls a carrot out of the ground, George can't believe it! George wants to grow his own carrots. Armed with a packet of carrot seeds, and guidance from the Man with the Yellow Hat, George plants his garden. After 66 days of tending, watering and keeping Jumpy away, George has a prize-winning carrot! It's so perfect in size, shape, and color, that George carries it around in a fancy telescope case to protect it. George visits Bill's house to show it off, and he learns that the bunnies have gone missing! George joins the search and finds them hungry and scared in a cave. It's a hard decision to make, but George sacrifices his perfect carrot for the bunnies to eat while he finds help. Thanks to George and his "carroty hero," the bunnies are saved and fed.

George and the Man with the Yellow hat are lending a hand picking apples at Renkins' Farm, George takes an apple coveted by Jumpy Squirrel, who snatches it back and hides in the barn. George follows, and when he reaches for the light switch, accidentally turns on the giant cider press! All of the apples they've collected are being washed, chopped, and squished into liquid! Not wanting the Renkins to be mad with the sticky mess, George fills everything he can get his hands on with the apple juice squirting out of the machine. When the Man with the Yellow Hat and Renkins' arrive, they're astonished to see the entire harvest bottled up! Much to George's relief, the Renkins aren't upset — they're thrilled. And Jumpy, much to his relief, finds his perfect apple.

It's the hottest day of the year, and to cool down, George wants to build a snowman! But how can he build a snowman when there's no snow? George experiments with crushed ice cubes, but they melt too quickly. Mud... but it doesn't stay in the right shape. And rocks, which are too heavy to lift! George is stumped. What sticks together, doesn't melt, and wasn't heavy? Of course, sand! George convinces the Man with the Yellow Hat to drive him, Bill, and the Renkins to the beach, where they can all cool off and George can finally build his summer snowman.

George loves feeding the birds, but they must be starving, because all the seeds keep disappearing! Perplexed, George returns with more food, only to find a big, bushy tail sticking out of the feeder. It's Jumpy Squirrel, caught in the act of eating all the seeds! George tries to squirrel-proof the birdhouse, moving it further from the tree trunk, clearing away freestanding objects, and even developing a pulley laundry line system to hang it from. But to no avail - that squirrel can climb - and apparently eat - anything! Why does Jumpy keep taking the seeds? Has his appetite suddenly grown — or maybe they're not all for him?

Professor Wiseman needs the Man with the Yellow Hat's help to assemble some rare dinosaur bones into a skeleton in time for an important archaeologist, Dr. Raj Desai, to see them. Wiseman and the Man finish the task and meet Dr. Desai for lunch. Meanwhile, George and Gnocchi play outside with a toy plane, which floats though a window--landing on the newly assembled dinosaur. When George climbs the fragile bones to retrieve it, the entire skeleton collapses! Using another dinosaur as a model, George is able to organize, sort, and piece together the bones back into its proper form. But how will Dr. Desai feel about a monkey working on his precious dinosaur bones, especially when the wrong head ends up on the dinosaur's skeleton?

The secret to Bill's amazing garden is the compost he uses to feed his plants. George decides to make compost for his hungry plants...so George empties the entire contents of his fridge in the backyard. The next morning, George realizes that instead of making plant food, he's made a stinky mess! The Renkins teach George that proper compost consists of dirt, water, and air with only certain foods (no meat or dairy). Back at the apartment in the city, George sees that all the plants need food. George prepares a hearty "meal" ...using every container that he can find. When the Man with the Yellow Hat wakes up to an unusual smell, he follows his nose to the compost! To the neighbors' delight, George made enough for all the plants in the building.

It's "Reuse Your Junk Day" and George and the Man with the Yellow Hat have one last pickup before they go to the lake. But when they arrive at Renkins' Farm, they find a mountain of junk piled in the Renkins' living room. There's no way they'll finish the job before the suns goes down, which means no lake for George. While the Man is taking a load to the collection center, George discovers that he can use the ironing board as a lever to launch the junk out of the living room and onto the front yard. Soon, all the pigs, chickens, and squirrels are ducking for cover! George's ingenious invention got all the junk outside, but it's scattered everywhere! Did this little monkey cause more work for himself?

George is an expert at navigating the maze on the placemat at the Y-Go-By Diner, but his skills are put to the ultimate test when the Man with the Yellow Hat takes him to the Annual Amazing Maze Race at Renkins Farm. The Man and George follow their map precisely, but how can they compete with the Quint's computerized navigation device, Bill's system of leaving a trail of corn, and Sprint's speedy disposition? It's not until George gets a bird's eye view of the maze that he is able to line up the landmarks on the map and figure out where to go. But when Leslie the cow eats their map, they need to figure out a more creative way to get to the finish line!

After a bubble bath, George promises the Man with the Yellow Hat that he will stay clean until their picture is taken for the cover of Bird Watchers Magazine. But when George helps Steve and Betsy dye eggs, he falls into a pot of food coloring, and turns completely yellow! Trying to keep his pledge of staying clean, he experiments with the different dye colors to see which ones he can mix with yellow to turn him brown again. In the process, George turns himself orange, Charkie turns blue, and Compass turns red! Can George figure out how to get back to his original color, or will the bird watchers return to find a rainbow colored monkey?

After warning George about the poison ivy lurking in the park, the Man with the Yellow Hat loses his balance and lands hands first in a brush of the itchy, poisonous leaves! With his hands bandaged, he'll need help with everyday tasks such as brushing his teeth, making dinner, even typing a letter. So being a clever little monkey, George invents some ingenious ways to make the Man's life seem normal — like wearing swim fins to assist in picking apples off the floor and taping salad forks to his arms to act as temporary hands. But George's creations are put to the ultimate test when the Man has to present Professor Wiseman's newest invention to the science board, salad forks and all!

Mr. Glass' unique version of Groundhog Day is an annual city tradition of predicting when winter will start. Every year on the last Wednesday of August, Sherry the Whistlepig emerges from her burrow. If she sees her shadow, it means cold weather is coming. But what makes Sherry's shadow so special? To find out, George and his animal friends camp out at Sherry's burrow, but fall asleep while waiting for her to wake up. At the shadow ceremony, Mr. Glass mistakes a sleeping George and each one of his friends for a whistlepig and presents them for the world to see. But does a monkey, dog, cat, or pigeon shadow count?

Why is Bill yelling at a mound of dirt? He's worm racing! George turns to a pile of decomposed leaves to find his own prize worm and challenges Bill's "Fast Freddy" to a race. Pretty soon, the entire countryside catches worm-racing fever and watch as George's worm, named "Ooh Ooh Ahh Ahh," races its way to the championship. But when Mr. Quint takes the wrong lunchbox on his fishing trip, George's worm farm is in danger of becoming fish bait! Can George save his slimy friends in time for the championship race?

The city is awarding the "Golden Arrows Award" to the building that collects the most recycling. George is eager to help—once he learns what recycling actually is, of course. The building's Doorwoman next door turns out to be tough competition, so George hunts down recycling materials from everywhere he can think of. The only problem is, he doesn't know that he only recycle products after they've been used! Will the tenants with the missing recyclables forgive a monkey who's not just trying to win a contest, but also save the environment?

The Man With The Yellow Hat is running late to an appointment to show an important scientist some of his work, so he and George decide to take the bus to his appointment. But when George wanders off of the bus to get a map of the bus routes and the Man follows, leaving his work on the bus, they both wind up splitting up and each trying to find a way to find the bus and retrieve his work all while trying to arrive to his appointment on time.

George and the Man offer to grow vegetables to help Chef Pisghetti, whose restaurant never has enough. Compass and his pigeon friends, however, chow down on the seeds, causing George to dump what's left into a jar for safekeeping.

The toy store introduces a new toy called the Super Fun-Ball and a contest. Whoever can guess how many Fun-balls are in a display case closest to the actual number will win the display. So, George finds a container of about the same size as the display case and fills it with marbles about the same size as the fun balls. Doing so, George hopes he can win the contest.

After George hears the legend that a red sunset means a day of good weather and sees The Man With The Yellow Hat painting a red sunset picture, George decides to draw pictures of the clouds and watch their movement to predict the weather. He soon also learns that other animals have way of predicting the weather, such as the speed of a cricket chirping. Soon, he learns how people predict the weather.

George, The Man, The Doorman, and Hundley go out on the sea for a day on the doorman's sailboat. But, when the boat sail breaks, the group stops at an artificially rendered tropical island to look for parts to fix it. Soon, George's curiosity and Hundley's habit to keep everything neat and orderly causes the boat to wash out to shore with them in it. They find their way back to the island but must now find The Man With The Yellow Hat and The Doorman.

On a weekend trip to the country with Steve, Betsy, and Charkie, George hears a story about a pot of gold at the end of the rainbow and waits to see one to find out if the story is true.
