La Professoressa Wiseman incarica George e l'Uomo dal cappello giallo di scoprire dove nidifica una particolare specie di pinguino artico, e i due si avventurano fra i ghiacci per quella che si rivelerà una missione ben più complessa del previsto.

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.

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.

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?

Come fa Bill ad avere un giardino così rigoglioso? Il segreto è il compost, vero nutrimento per le piante! Dopo che Bill gli ha spiegato di cosa si tratta, George decide di creare da sè il cibo per le sue piante affamate, ma la ricetta ha bisogno di qualche ritocco...

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 è un campione nel trovare l'uscita dal labirinto disegnato sulle tovagliette segnaposto del ristorante, ma saprà orientarsi altrettanto bene in un labirinto di mais? L'annuale gara alla fattoria dei Renkins è l'occasione per dimostrarlo.

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?

Dopo aver avvertito George di stare alla larga dall'edera velenosa, pianta estremamente urticante, l'Uomo dal cappello giallo ci finisce dritto in mezzo.

To find out, George and his animal friends camp out at Sherry's burrow, but fall asleep while waiting for her to wake up.

The only problem is, he doesn't know that he only recycle products after they've been used!
