Gumball and Darwin waited 7 long months (long enough for hair to grow on Darwin's legs) to receive a video game, and they have finally received it. Excitedly, the boys open the disk slot on their game system and try to fit in the game, only to find that the game is in a cartridge, katriji ya and won't work with their system. Disappointed, they set off to the video game store to get a refund. Once they arrive at Ripley 2000, they ask Larry for a refund, to which he states that he can't give no matter how much he wants to. Larry says he isn't allowed to give refunds, and his boss is watching him through a security camera. The boys become upset and swear to get the refund out of Larry.
They then leave, only to return and nonchalantly ask Larry for a refund, which he refuses to give. The Ripley 2000 Manager then calls Larry, where he says that he did not give the refund.

The inayofuata ploy involves Gumball imitating the police using a bullhorn. At first, Larry is intimidated, but then he realizes that the boys are not actually the police and busts them, after telling them that he cannot give a refund. The boys then try to hypnotize Larry, but this proves to be a waste of time after he refuses to give them a refund. After that, the boys try again using sympathy. They pull out a TV and onyesha Larry a video about the "hundreds of children that buy computer games and don't receive refunds", featuring a kid named "Jimmy" (portrayed kwa Anais), who lives in a shoebox and a sad song about the children who have wasted their money on bad video games. Larry feels very guilty as a result, but still refuses the boys a refund.

Richard says he will handle the problem. He puts on a biker jacket, draws a tattoo, and grows a mustache to look intimidating, then goes to the duka to try and intimidate Larry into giving him a refund. When that doesn't work, he places the game on the counter and takes money from the cash register, which calls out the manager. Larry manages to escape, but Richard and the boys are trapped. The shadow on the door shows a frightening, large puffy monster, but the door opens and reveals a small, cute kubeba as the manager.

Richard laughs and makes fun of him, and asks for a refund, which causes the kubeba to attack him kwa biting him and crawling on him. Gumball and Darwin freeze, laughing at Richard, before they dash into the manager's office. Richard is losing the fight when Gumball and Darwin come out of the office with a security tape, which they blackmail the kubeba with. Suddenly, appearing to be in a nicer mood, the kubeba offers the three a 1% discount on a game system for the game (which the three find a bargain).

The game system is purchased and taken home, only for the three to find that the manager had ripped them off with a paper shredder.
