is the thirty-fourth episode of season two of The Amazing World of Gumball
. It is the seventieth episode overall.
Gumball and Darwin try to understand Juke's urgent beatbox message.
Gumball and Darwin are at the school playground, making fun of everyone, when Juke rushes to them. He tries to communicate, but they can't decipher his beatboxing. Gumball states he is not interested in helping Juke, but Darwin insists on doing so.
They head for the library in order to translate Juke's beatbox. While researching, Gumball continues to be insensitive toward Juke, and Darwin calls him out for that. They attempt to use online translator several times, and when the results come back as "The reign of the ape is no more," Gumball and Darwin take it to be the announcement of Miss Simian's retirement. They wildly run around the school and the world, celebrating her retirement. The other students -- and faculty members -- join their celebration, only to discover Miss Simian has no plans for retirement.
Gumball is fed up with Juke's continued attempts to communicate, when Alan comes to them. He knows a little beatbox, but is unable to successfully decipher his message. However, he believes he is repeating "Grobblefest." Gumball and Darwin return to the library to find out more about Grobblefest, supposedly a coming of age ritual for inhabitants of Boomboxembourg, Juke's home country. Once again, Gumball expresses his indifference, and Darwin calls him out again. After they communicate their feelings using a series of viral videos, Gumball finally gives in and avows to help Juke.
Gumball and Darwin then initiate Juke into Grobblefest, but Juke seems to be confused and unwilling as they force him through a series of strange rituals. Eventually they all end up at the Wattersons' backyard for the final stage of Grobblefest, called "Grobblefight" (albeit with a pair of shoes, a bag of oranges and a garbage can lid instead of the real weapons). Gumball and Darwin get into a huge argument about helping people for the sake of feeling superior. Darwin flings oranges at Gumball, who deflects them with the garbage can lid. One of the oranges hits Juke in the back of his head, turning his switch from "Music" to "Voice," which effectively enables him to speak English. Juke thanks the boys, and explains that he has been trying to ask people to turn his switch for two years, and that he apparently doesn't know what Grobblefest is. Unfortunately, Gumball and Darwin fail to hear him, and as they make up with each other, Gumball accidentally runs his hand down Juke's switch, reverting his speech to beatbox.

- The "crying... FOREVER" video is similar to a popular .gif of an asian man crying.
- The "Little Timmy fell down a well" joke is a reference to the 1954 TV show Lassie. It was used before in "The Sock".
- Gumball's "You found the treasure, and now we can save the town from the evil contractors" line might be a reference to The Goonies.
- When Gumball tries to sing the squirrel a lullaby, the last part sounds like "Zelda's Lullaby" from the Legend of Zelda video game series.
