The episode begins with Richard washing his face to prepare for the day. Gumball and Darwin walk in, and make fun of him for being fat. Nicole comes in and asks what they said to him. They say it was a trap and start making fun of her for being old. Nicole then leaves angrily. The boys begin to notice how they are not growing up and agree that they will be young forever. Darwin says they will never change, but as he says "change", his voice rapidly begins to change pitch. Gumball asks if he is alright, only to have his voice become so low that the bathroom shakes. Gumball concludes, in an extremely low voice that destroys the bathroom, that their voices are broken.
Gumball then decides to call Penny. Her dad answers the phone, and Gumball asks if he can speak to Penny while his voice is cracking. Penny's dad assumes that Gumball is a prank caller who is trying to freak him out. Mr. Fitzgerald talks in a scary voice and warns Gumball. While he is talking, the left side of the screen enlarges and squishes Gumball's head on the right side of the screen. He hangs up, and decides that he and Darwin should just go to school.
When they go inside the school bus, Darwin asks for tickets in a deep voice. The bus driver then gets mad and they can't go without weapons. Gumball tells the driver that he and Darwin are just kids, but says it in a deep voice, which causes the driver to believe they're not kids. Gumball and Darwin then decide to just walk to school. They then stop by a store and Darwin sees a poster of a half-price sale of double chocolate chip cookies, and wants to buy those cookies.
Darwin then walks in to ask Larry where the double chocolate chip cookies are, and yells, "HEY!" which startles Larry and causes him to get mad. Darwin keeps yelling, and Larry threatens to call the security guard. Gumball asks what's going on, and Darwin tells him that he can't control the volume of his voice. Gumball yells, and the security guard comes, asking him and Darwin to leave. They leave, and Gumball gets angry at his voice, causing him to punch himself until he can only wheeze. A car comes with Penny and her dad in it. Penny asks Gumball what's going on, and Gumball tries to talk to her, but he can only wheeze. Penny's dad then talks to Gumball in a scary voice on how he has a set of skills. Gumball closes the window and shuts the door since he's already heard this from the phone call. Gumball then tells Darwin that they might need to go to a doctor. Since Gumball wheezed and Darwin can't understand him, he punches himself and repeats what Gumball said while wheezing.
Gumball and Darwin then go to the hospital and asks him why their voices are broken. The nurse laughs and says that their voice are breaking, not broken, and tells them they are growing up, and only a small percentage of people in the world never grow up. Shortly after that, Gumball and Darwin are seen walking home, and Darwin asks him what he would do if he knew if his childhood days are over. Gumball says he would lie on the ground and cry, which is exactly what he does. Darwin then slaps Gumball in the face, says no, and that they should make the most of it. Then they sing the rap, "Make The Most of It", and they are shown doing typical kid stuff. After the rap, Gumball and Darwin's voices go extremely low. They then rap in their deep voices. A kid and his mother assume that Gumball and Darwin are short men pretending to be kids. After hearing this, Gumball and Darwin walk in a gray area. Gumball cries, and Darwin says it's over and they're not kids anymore.
They then sing another song in their deep voices. When they triumphantly start singing about the benefits of growing up, the area turns colorful and their voices change so that they sound younger than before. Gumball is confused, and Darwin then realizes that he and Gumball are in the 1% of people on the earth who never grow old. The episode ends with them extremely happy that they're going to be kids forever, but then suddenly realize how boring it would be and lost their enthusiasm.
