La professoressa Wiseman deve partecipare a una maratona di beneficenza per sovvenzionare un viaggio di studio. Assolutamente non avvezza a queste esperienze, la Wiseman chiede aiuto a Ted per allenarsi... ma dal momento che questi si è infortunato, alla fine la professoressa potrà contare solo su George.

George has just been made an Honorary Junior Sprout of Country County and is thrilled to be on his first trip with the troop. But when the troop gets lost in the woods, George not only finds himself separated from the group but he also discovers a man sawing branches off a tree — a clear violation of Sprout rules! Can George prevent the man from harming more trees and earn his Sprout stripes along the way?

Armed with a cool new monkey-sized vacuum, George watches with amazement as his new "toy" sucks up everything in sight... including some of Mr. Stamp's rare stamps! Inspired by a TV superhero, George dons a cape and embarks on a citywide "cleaning" spree, using his little vacuum to suck up everything from bird food to dog biscuits to a winning lottery ticket. When the townspeople can't catch up to the cleaning monkey, will they view George as a Superhero Vacuum Monkey or a Super Villain?

George conosce una nuova amica che si chiama Allie Whoops e con lei cercherà di fare amicizia con uno scoiattolo e passerà una giornata piena di emozioni.

Hundley takes it upon himself to return the toy a baby dropped in his lobby. But when George sees Hundley racing down the street with the toy in his mouth, George thinks he wants to play, and this delays Hundley. Hundley is not happy to see the baby drive off in a bus sans toy and is even more upset when Gnocchi, who wants in on the fun, grabs the toy and disappears through Pisghetti's basement window. George and Hundley follow Gnocchi into the basement, only to have the door lock behind them. Uh-oh. George and Gnocchi can climb up and out the window, but Hundley can't. George comes to the rescue by constructing a ramp leading to the window that even the littlest Dachshund legs can climb. Now they just need to figure out where that baby went.

Sotto casa di George arriva un nuovo mercatino settimanale. Fra i commercianti, c'è anche Juice Jay che prepara un succo di frutta in grado di lasciare a bocca aperta sia la scimmietta che l'Uomo dal Cappello Giallo. Non volendo aspettare una settimana per assaggiarlo ancora, George prova a preparare il succo da solo.

George vorrebbe aiutare Ted a far conoscere e vendere il suo libro dedicato a un uccello a rischio di estinzione. Non resta che trovare il modo di pubblicizzarlo a tutta la città.

George non si sente molto bene. C'è un battere che indugia nel suo corpo e che lo fa starnutire e tossire, e allo stesso tempo lo rende molto assonnato.

A dry spell has lowered the water level of Lake Wanasink Lake, which leaves one of George and Allie's fish friends trapped in a small pond away from its family! George digs a canal with a lock between the lake and the little pond, but he can't get his fish friend to use it. Can a monkey and girl find another way to get the fish back to its family?

George viene invitato da Allie a fare l'ospite d'onore al suo asilo e riscuote un grande successo.

Charkie is at a dog obedience class, and the next day is the final test! Since Betsy has a concert, George (and Hundley) must recreate the obstacle course and make sure Charkie can do it in under a minute to pass.

Ted e George convincono la professoressa Wiseman a staccare la spina dal lavoro e a prendersi una giornata di relax. Purtroppo, durante il periodo del previsto relax si creeranno numerosi contrattempi ai quali dovrà essere proprio la professoressa a rimediare. Ma sarà comunque un giorno molto riposante, per lei.

Charkie will do anything to get what's inside of Aunt Margaret's parcel, but George promised he'd keep it safe! After twisting, turning, flipping, and rotating the box, George is able to get it out of sight, but Charkie's keen sense of smell makes it impossible to stay hidden for long. Can George figure out how to distract Charkie's super sense long enough to get the box back to Aunt Margaret?

Lo chef Pischetti vuole battere il rec ord mondiale dello spaghetto più lungo del mondo e chiede aiuto a George per misurarlo.

It is the hottest day in the city and the city keeps suffering from blackouts. But there is one place left with electricity: the museum which just converted to being entirely powered by solar power. When George learns how the sun's light can be absorbed and turned into electricity, to do things like charge batteries, he tries to charge up several things at home such as his toy UFO or the cordless phone. But then he learns how solar power really works to make electricity. Then, when another blackout makes the Man unable to cook his lasagna for the museum's big power upgarde party, he and George learn that the sun's heat can also be used to cook things.

Il signor Glass vuole edificare un parcheggio al posto di un vecchio cinema dismesso. George, Myh, e un ex-dipendente del cinema decidono di salvarlo dalla distruzione e organizzano una serata speciale.

Professor Wiseman wants to makes something creative for the bake sale at Betsy's school. But she believes that the key to cooking is to experiment with different amounts of different ingredients and as a result her cakes come out floppy, gross, and VERY sticky. When Professor Wiseman and George visit Chef Pisghetti he says that cooking is not about testing and experimenting like science and you need to follow a recipe exactly for the food to come out right.
