SpongeBob walks outside to breathe in the peacefulness of the neighborhood. Suddenly, he loudly begins to build a bubblestand, much to the dismay and annoyance of Squidward. At the stand, SpongeBob offers to teach how to blow bubbles for twenty-five cents. The noise disturbs Squidward, who demands SpongeBob to be quiet. Patrick comes out, comes to the stand, and asks to try it out. Patrick only buzzes his lips instead of blowing, failing to blow a bubble. SpongeBob offers to teach him for an extra quarter. SpongeBob shows how he blows bubbles with a peculiarly entertaining, yet somewhat peculiar, technique. When he shows Patrick, SpongeBob blows a duck bubble, an ice cube bubble, a caterpillar bubble, and a boat bubble.
Then, after all the bubbles pop, SpongeBob then uses two hands to blow a bubble elephant, Patrick calls it a "giraffe," The elephant (or giraffe) flies into Squidward's window and pops inside the house causing an explosion. Squidward, enraged, comes out and demands to know how they are making so much noise just blowing bubbles. SpongeBob shows him the technique and blows a butterfly bubble, but Squidward angrily rejects SpongeBob's ideas and shoos SpongeBob and Patrick back into their houses in embarrassment. However, Squidward begins to blow a bubble out of curiosity, but SpongeBob and Patrick return to ask for payment. Squidward reluctantly has to give them 25 cents for the bubble.
Squidward attempts to impress the two with his technique, but instead fails, with each bubble falling to the ground. While Squidward still attempts to blow a satisfactory bubble (and, as a result, spends more money with each bubble he blows), SpongeBob and Patrick try to convince Squidward to use the technique. Finally, Squidward, furiously (though without realizing it) copies their technique in an attempt to mock them. However, he blows an enormous bubble by screaming in anger. SpongeBob and Patrick then congratulate Squidward, saying that he is "amazing," and that his bubble was the best. Squidward thanks them sarcastically and leaves, walking back into his house. He begins to play his clarinet, with SpongeBob and Patrick chanting his name. However, the gigantic bubble floats and traps Squidward's house inside it, unearthing it, and sending it up in the air.
SpongeBob and Patrick try to warn Squidward, but Squidward thinks they're still chanting him and keeps playing, thinking he is "amazing." When he looks outside, he sees himself way way above the ground with SpongeBob and Patrick specks on the ground. The bubble then pops, which then shakes the ground, sending his house back to its original area, albeit with much force. SpongeBob and Patrick look at each other nervously and they retreat to their houses before Squidward can scold them.
