Monkey Underground

George arrives in the country for some of the Renkins' fresh blueberries but soon finds out something else: Mrs. Renkins is setting up a hot air balloon. She offers to take George and the Man up and down a few times. Soon, Bill shows up and he and George accidentally send the balloon skyward an untether it. George and Bill are then left soaring across the country sky and have no clue how to stop and land.

George is in the country eating a sandwich when he sees a strange-looking animal stealing his food! After trying to scare it away he winds up getting sprayed with a stinky fluid. The Man tells George that the animal he met was a skunk and that they spray to defend themselves. Bill finds the skunk to be living under his front porch and seals up its home. That leaves the skunk to nestle in the basket George and the Man brought to the country and they wind up accidentally bringing it home to the city.

The Renkins' are having a problem with their grape yard. A group of gophers have made their home in the ground under the garden and are stealing the grapes. Upset with the problem, Mr. Renkins calls Calhoun the Gopher-getter, an exterminator, to come and catch the gophers. George does not like the idea of somebody catching the innocent gophers, even if he does plan to release them again. So he decides to build a connecting tunnel between his house and the Renkins' garden so the gophers can escape.

George has another job in the city. He has to take care of Professor Wiseman's new kitten, Lucky for a day. Lucky appears to have a crush on Hundley, which is unfortunate because Hundley is allergic to cats. When the Doorman tells George to keep Lucky away, he decides to build a version of Hundley which will not make Lucky sneeze. When things do not work out, George decides to use something of Hundley's, making him mad. When Lucky hears Hundley barking through the air vent, she goes inside the walls of the apartment to try to find him.

The Man in the yellow hat is trying to get ready for his photo on his new licence but when George tries to help, the ensuing chaos ruins the Man's hat! The hat is cleaned and restored like new and the Man puts it on the kitchen counter right next to an identical looking box of trash. In a rush, George accidentally throws out the box with the hat and must go on a city-wide spree to find it. Unfortunately it seems like every trash can and dumpster in the city George finds has already been emptied by the garbage truck. George finds some disposed items at Pisghetti's restaurant but Chef Pisghetti tells him that it is not trash, it is recycling. He tells George to go look for the hat in the landfill.

She entrusts George and Steve to get the xylophone to the school. Unfortunately when George knocks the xylophone over he must put it back together. He remembers how the notes, when played in order, sound like they are climbing stairs. But it seems like no matter how he sets up the bars, he can't get them in order. He realizes he needs to count in order from one to set up the xylophone properly. But George cannot count past 12 and the xylophone has more pieces than that.

The Man in the yellow hat is competing in the country town bowling tournament at Bowlmore Lanes but it seems like George does not have any luck getting the ball to hit the pins because it keeps falling into the gutter. When he sees The Man polishing his bowling shoes because they make it extra lucky, George decides to polish his bowling ball too. After George polishes the ball he decides to give it a test roll.

George and The Man run into Steve at the local movie theater taking down signs for the old movies, which the manager lets him have.

When he goes back out to look for more, he notices the park in chaos. Realizing that it is because the signs are gone, he decides to put them back. George puts back all of the signs but does not put them in their original places causing more chaos. The Man then tells George that each sign has a meaning and they are not just for decoration.

Mr. Glass buys one of her paintings and brings it back to the Glass Palace but Charkie accidentally rips it. George has to get a replacement painting but it turns out that every painting Soo Berm makes is unique and one-of-a-kind. This leaves George to make his own copy of the painting.

George must find a way to break Hundley out of the animal shelter.

George must also figure out a plan to sneak in, free Hundley, and sneak out.

George's room is getting very messy and George needs to clean it. The only problem is that when George crams everything into his closet, it just spills back out. Later on at the local supermarket, he sees the grocer's son practicing for a grocery bagging competition. He explains to George that a lot of stuff can fit into one small bag if it is put in just right, somewhat like putting together a puzzle.

He then enlists George to compete for him in the competition and must train him to bag properly.
