During a blustery day in the Hundred Acre Wood, the hole to Gopher's tunnel (which is revealed to be a portable hole) gets blown away by the strong breeze. In another part of the Woods, Pooh, Piglet and Tigger are all playing with bubbles while Rabbit comes to call their attention about the lecture they will have later, entitled “Our Friend, the Lima Bean.” Gopher approaches them as he is searching for the hole. Rabbit dismisses Gopher’s hole search as “silly” and heads back to his home to prepare for the lecture. As both Rabbit and Gopher leave, Tigger comes up with the idea of making a bubble that can’t be popped. He successfully makes the bubble using an unusual recipe, but ends up trapping Pooh in it. Being unable to escape from the bubble, Pooh cannot control his movement, and ends up hurting Gopher, who continues the pursuit of the hole, a couple of times.
While trapped inside the bubble, Piglet lets Pooh stay in his house, but Pooh ends messing up his home. Piglet suggests Pooh to go to Tigger's house, but the same thing happens. Unable to think of a solution, Tigger secretly puts Pooh and the bubble in Rabbit’s house and as a result, Pooh ruins Rabbit’s lecture preparation. Annoyed, Rabbit decides to hang the bubble on a tree and paints it to resemble a gigantic apple. Afterwards, Rabbit leaves along with Tigger and Piglet, and tells the latter about excluding Pooh from his lecture.
As the lecture begins, it starts to rain, and the paint on Pooh's bubble has washed off. A very sad Pooh mutters how he wishes he wasn't a nuisance and worries he'll be trapped in the bubble forever. Gopher arrives, still looking for the hole, who apparently has started to literally "comb" the forest. After hearing his story, Gopher sympathizes with Pooh, saying they’re “kinda unwelcome these days”. Incidentally, Pooh reveals he was the one who found Gopher’s portable hole (which he kept in his pocket for a while) and uses it to be free of the bubble under Gopher's suggestion. Afterwards, a joyful Pooh heads to Rabbit’s house and interrupts his lecture to announce the news. Piglet and Tigger, both relieved, ask for Pooh’s forgiveness for caring him less just because he was stuck in a bubble, but Pooh doesn't mind. Rabbit was less enthusiastic of it, and tells Gopher for “no more hole silliness”. The episode ends with Gopher tricking Rabbit into falling into the hole as a vengeance prank.
