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 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.
