"Vegetables" is the sixteenth episode of Season 2 of Teen Titans Go! and the sixty-eighth episode overall. It first aired on 9 October 2014 on Cartoon Network.
Beast Boy's healthiness persuades the other Titans into becoming vegetarians, but the converts take their new dietary restrictions a little too seriously.
At the Titans Tower, Robin is fixing his grappling hook, Starfire is tickling Silkie, Raven is reading a book, and Beast Boy is playing video games when Beast Boy asks for the time. Cyborg answers that it's Meat Party Time and the Titans head outside where Robin, Starfire, and Raven are served with piles of meat. Beast Boy tells Cyborg to throw his vegetables on the grill, but the robot declines. Robin questions why Beast Boy would want vegetables and he answers that he's a vegetarian. Cyborg attempts to give him some meat, but Beast Boy declines and offers his teammates vegetables. The Titans ignore him and continue to stuff their faces with meat when Robin receives a crime alert on his communicator. He tells the Titans to prepare for a meat-fueled melee against Cinderblock.
At Jump City, Cyborg attempts to charge Cinderblock, but he, Robin, Starfire, and Raven collapse on the floor because of their excessive meat eating which resulted in meat guts. Raven notes that her meat gut developed a living personality. Beast Boy, still in shape because of the vegetables, decides to take on Cinderblock on his own and successfully beats the villain with the Titans commenting on his alertness and energy. Robin asks Beast Boy for the reasoning behind his focus and agility and Beast Boy answers that it's because of vegetables.
Back at Titans Tower, Beast Boy is educating the Titans about vegetables, but each one assume that all vegetables are carrots. Cyborg complains that knowing the different types of vegetables is confusing and Robin tells Beast Boy that all vegetables are tasteless rabbit food. Raven and Starfire agree with Robin with Raven saying she shouldn't eat like a rabbit if she's not one and Starfire claiming that vegetables do not taste as good as meat. Beast Boy hands the Titans different plates of vegetables to show them that vegetables can be delicious, but the Titans are skeptical. They each take a bite and are amazed by its deliciousness. The Titans embark on a vegetable-eating voyage when Robin gets a crime alert.
At Jump City, Thugs are robbing Jump City Bank when they spot the Teen Titans. Cyborg eats spinach which causes him to grow muscles and beat up one of the thugs effortlessly. Robin bites a carrot and gains super sight. He throws a birdarang in front of a thug's feet, causing him to trip. Starfire, energetic, rapidly tells the last thug about her energy and spins him around until throwing him in front of Raven. Raven claims to be happier than ever and slams the thug a few times before throwing him into the back of a truck with the others. Beast Boy compliments the Titans' performance and tells them to look underneath their shirts where they discover they have abs and are sweating honey. Starfire decides to only eat vegetables from that day on, and is joined by Robin, Cyborg, and Raven.
Three weeks later, Beast Boy walks into the kitchen and notices that the Titans' skin have turned bright green and they hypnotically offer him vegetables. Beast Boy tells them that they're green and Cyborg claims it's because they're vegetarians. Beast Boy informs them that vegetarians don't turn green, but Robin says that Beast Boy is green. Frustrated, Beast Boy tells the Titans that they should eat in moderation and takes out an apple. The Titans confront him and Raven tells Beast Boy he can't eat that. Beast Boy says it's just a fruit, which Robin claims is a type of meat. Starfire asks if an apple is a vegetable and when Beast Boy says no, the Titans believe he is eating meat. Raven decides to take him to their master and she and Robin stuff Beast Boy into a bag.
Somewhere underground, Beast Boy wakes up chained to the floor. He looks up to see the Titans in green cloaks chanting "vegetables". Cyborg informs Beast Boy that ever since they ate their first vegetable, their master whispered into their ears and Starfire claims that he would grant them a place in his Vegetable Kingdom. Robin orders them to be quiet and the Titans recite a chant to grant them their master, a giant carrot named Vegetor. Vegetor announces that he would destroy all meat in the universe, starting with Beast Boy and telekinetically raises a giant eggplant to crush Beast Boy.
Beast Boy transforms into a gorilla, breaking his chains, and grabs the eggplant. He informs them that he is a vegetarian and attempts to reason with his friends as the eggplant continues to try and crush him. Beast Boy struggles to lift the eggplant as it descends and he asks Cyborg for the time. Cyborg says he doesn't know due to lacking a watch and guesses that it's sixish. As the eggplant prepares to crush Beast Boy, Cyborg realizes that it's Meat Party Time and shoots meat into the other Titans, curing them of their brainwashing. Vegetor gloats about Beast Boy's defeat, but is distracted by the smell of meat. He initially refuses to eat meat, but takes one bite and becomes smitten with it. The Titans and Vegetor embark on a meat voyage, but gain meat guts. Beast Boy tells the Titans that it's their chance to take him down, but Vegetor explodes, splattering the Titans with a mixture of meat and vegetables. Beast Boy is disgusted by the meat while Raven is disturbed by the vegetables. Cyborg jokes "that's what I call a balanced diet" and the Titans, and Raven's living meat gut laugh as a result.
