"Missing" is the forty-sixth episode of Season 1 of Teen Titans Go! and the forty-sixth episode overall. It first aired on 26 March 2014 on Cartoon Network.
Cyborg, Beast Boy, and Robin return Silkie to Killer Moth to collect a cash reward. Starfire is devastated until she sees Killer Moth might love Silkie just as much as she does.
Aqualad begins performing a DJ concert much to the excitement of Robin, Beast Boy, and Cyborg, who are dancing in an alley next to the concert hall. The three express their happiness at being at the concert for free and mock the ones inside who had to pay for tickets. Hungry, the male Titans decide to go for a snack bar run and arrive at the Dumpster Diner where Beast Boy is given an old banana and Cyborg is given a half-eaten hot dog. The three finish their dinner when Robin asks Cyborg for a "wall napkin" which is actually a missing poster for Silkie from Killer Moth. Robin and Cyborg scoff at the request, claiming they'll never return Silkie to a villainous evil and crush Starfire. Beast Boy expresses doubt that the poster was written by Killer Moth but by a snake due to the dollar signs which Robin explains as a cash reward for Silkie. Excited by the cash reward, Robin, Beast Boy, and Cyborg convince themselves that Killer Moth must really want Silkie back and resolve to return him as it's the "right thing to do."
At Titans Tower, Starfire finishes reading a tale regarding a princess who mercilessly destroyed her suitors to Silkie who proceeds to sleep. The Tamaranean reveals it is time for Silkie's bath and begins to lick him. Raven enters and drops her food upon seeing Silkie's bath and claims it to be disgusting. Confused, Starfire wonders if bathing disgusts Raven before explaining that she uses her tongue as it yields the best results. She congratulates Silkie for being good and rewards him with zorkaberries which she bird-feeds into his mouth, disgusting Raven further as she claims that Silkie only loves the berries, not Starfire. She flees as Starfire resumes licking Silkie behind the ear.
Later that night, the male Titans park the T-Plane above the tower to begin their capture of Silkie. Cyborg cuts a hole through the tower glass and has Robin enter Starfire's room. He places Silkie in a bag and throws it to Cyborg, who yanks the rope to have Beast Boy hoist them up. The male Titans make their escape, but Robin drops the missing Silkie poster on Starfire's bedroom floor. In a hideout underneath Golden Gate Bridge, Killer Moth commands his moth minions to wreak havoc in the world. As they flee to carry out their mission, each and every one slam into the T-Plane which then crashes into the hideout. Killer Moth mistakes their intentions into one of battle, but Cyborg reveals they have come to return Silkie. Killer Moth displays an affection towards Silkie, thanking the Titans, but they claim it was the right thing to do. Killer Moth thanks them and bids them goodbye, but the male Titans wait until the villain decides to give them the cash reward.
Back at the tower, Starfire screams upon noticing that Silkie has gone missing and voices her opinion to Raven that a snake has stolen him based on the dollar signs. Raven reveals someone must have returned him to Killer Moth causing Starfire to exclaim that the villain will not treat him with kindness. Raven claims that Silkie is incapable of loving Starfire, but the Tamaranean cries her knowledge that Silkie loved her too before resuming her tears. At Justice Java, Robin, Beast Boy, and Cyborg are unable to determine how to spend their money. The three then decide to follow the footsteps of the richest man they know - Scrooge McDuck - and celebrate through a song.
In Raven's room, the half-demon is attempting to meditate when she is interrupted by Starfire licking her hood to get rid of the gunk. Disgusted, Raven tells Starfire she needs to move on and takes her to Killer Moth's hideout to prove that Silkie is happy with his rightful owner. Killer Moth shows his affection to Silkie by giving him tummy farts but reveals his true intentions to mutate him into a harbinger of destruction. Starfire and Raven reveal themselves, demanding Silkie's return, but the villain drops him into a pool of chemical mixture. At Jump City, the male Titans cheer their spoils the reward has brought them, but resolve to use the last of their money to amend their guilt and cheer up Starfire.
A mutated Silkie is told by Killer Moth to destroy Starfire and Raven, but he refuses to do so. Raven notes that Silkie can now talk as he celebrates. Killer Moth complains about his plan's failure and decides to go to bed. Silkie proclaims his love for Starfire and the two hug as Raven apologizes for her mistake. Silkie forgives her by stating he loves her too and offers them a ride. Taking to the skies, the three travel through the clouds and toward Jump City. On the streets, Robin, Beast Boy, and Cyborg express hope that Starfire would like the box of kittens they purchased before spotting the mutated Silkie. The three run into a dumpster and look on in terror as Silkie flies into the sun as a narrator reveals that Starfire and Silkie shared many adventures, but that it is not another story.
