Plot
The episode starts off with Robin, Cyborg, Beast Boy, and Raven enjoying their glasses of water. After taking a sip, Robin complimented how water was the "nectar of the Gods". Cyborg says he loves cold glasses of water on a warm day, Beast Boy says he loves drinking water to stay hydrated and Raven says she loves getting large amounts of water and holding it there so she could enjoy it's flavor and she takes a large sip while her cheeks enlarge into a ridiculous size. Suddenly, Starfire breaks down the door and enters the kitchen and alerts the other Titans that she has seen "the penguin", a "killer crocodile" and "the woman cat", loose in the city, causing the other Titans to spit out their mouths full of water and take charge. Thinking she was talking about the infamous well known villains, The Penguin, Killer Croc and Catwoman, Robin asks Starfire where she has seen them. Starfire tells him she will show him and blasts a hole with her starbolts through the kitchen wall.

In the next scene, Starfire leads them to the local zoo. Robin says he didn't see any sign of them. Starfire then says she has found them and points to an actual crocodile, actual penguins and an actual lioness. Cyborg clarifies she was talking about actual animals instead of the villains. Starfire questions if she was misunderstood and annoyingly Beast Boy responds she was, and angered that he spit out their good water, which also upsets the other Titans, leaving Starfire ashamed of herself.

The next scene is back at the Tower. Robin, Cyborg, Raven and Beast Boy are enjoying themselves in the living room while doing their own activity: Robin lifting weights, Cyborg playing on his communicator, Raven reading a book and Beast Boy keeping himself busy with one of those paddles that has a ball attached to it by a string. Starfire, with a sad expression, enters the room and falls flat on her face on the living room floor. Robin questions her actions and she apologizes for ruining their water enjoyment by her earlier misunderstandings. Raven tells her misunderstands are normal and that she should not worry about it. Beast Boy agrees and says he loves it when she talks bad. Starfire admits she wished she talked clearly and normally like they do.

Robin warns her if she changed the way she talked, it will affect who she is as an individual. Cyborg adds on it isn't something that she could just perfect over night. Starfire says she could, due to her Tamaranian ability through developing other peoples' speech and languages through lip contract. Excited, Robin asks her if she was talking about kissing and she nods her head. Then Robin claims if Starfire wants to communicate more clearly then as friends they should help her. Starfire gets excited but she can't decide whose speech patterns to pick up because she thinks they are all sounded appealing.

Cyborg suggests they could play "Spin the Bottle" to help her decide. Robin agrees and rushes to desperately find a bottle. He finds a soda bottle in the fridge and quickly joins the other Titans back into the living room. Annoyed, Cyborg tells him to calm down and Robin shouts at him by telling him to calm down. Robin spins the bottle and it lands on a cactus. Cyborg and Beast Boy teasingly tells him he has to kiss it. Raven puppets the cactus and have it flirt with Robin. Robin kisses it but gets pinched by one of it's needles. Beast Boy laughs and claims he has a crush on it. Robin disclaims and says he's way too attractive to date a cactus. The cactus pinches Robin for the second time and Robin, in pure anger, throws it out the window.

Next it's Starfire's turn to spin the bottle. She spins and it lands on Beast Boy. They kiss and she now sounds and acts exactly like him. She seems happy and Robin has a near breakdown as he runs to the kitchen to very loudly cry.

In the next scene Starfire (with Beast Boy's voice) flirts with a sun bathing Raven and talks to Cyborg about Aura's and metaphysical flow. Unfortunately they don't understand. Defeated, she returns to her normal voice and walks away. In the next scene Starfire is still down that even with Beast Boy's voice she could not be understood. Raven consults her that she shouldn't try to change her voice but she is insistent and Robin suggests another game of "Spin the Bottle".

Robin thinks he has the perfect formula and spins first landing on the cactus. The others make fun and Raven again puppets the cactus and they make him kiss it poking him and causing great pain. Next it is Starfire spins the bottle again and this time it lands on Cyborg. They kiss and she gets his voice and his personally and rush off to go watch "Family Matters" and excitedly talk about Urkel. She then goes into a long rant about two characters confusing Beast Boy and Raven. After she realizes she failed again she goes back to her normal voice.

Raven still says she shouldn't change her voice and Robin (who fell on the cactus with his lips) agrees but Starfire rushes out to kiss nearby beings including Sticky Joe, Pain Bot and Birdarang. She starts to short out and Raven explains that with each new personality her old one disappears and they all rush out to stop her from kissing anyone. Robin catches her and she tries to kiss him. The other Titans yell not to do it and he resists saying that Starfire shouldn't kiss him (and not just because him and the cactus have gotten serious) because they love her the way she is. The episode ends with her announcing that "the killer crocodile", "the woman cat", and "the penguin" were behind them. Raven says that their not falling for it and getting attacked by the villains from behind.

Trivia

 * Starfire is the only Titan who has kissed more than anyone on the team and in the series in general.
 * Beast Boy has kissed both his female teammates. Starfire in this episode and Raven in "Rocks and Water". Though his kiss with Starfire was only for the sake of her picking up his vocabulary skills rather than being anything romantic.
 * This isn't the first episode where "Spin the Bottle" was played in this series. Cyborg and Beast Boy's magical duplicates were also playing this game with each other in "Double Trouble".

Continuity

 * Starfire's ability to learn more languages and vocabulary skills through lip contact is brought up again. Previously Robin brought it up in "Baby Hands" at an attempt to get a kiss from Starfire.
 * This is the third time a Titan "falls for" an intimate object. Robin falling for a cactus in this episode, Beast Boy and Starfire both falling for a scratching post in "Matched" and Starfire "falling in love" with a pot of chili in "Nean".
 * Once again, the Titans fail to understand Cyborg's television references, as previously depicted in season one, in the episode, "Tower Power".

Errors

 * Robin seemed to be unaware of Starfire's ability to obtain vocabulary and speech patterns through lip contact, but he was well aware of this ability in "Baby Hands".
 * Raven doesn't seem to be jealous after Starfire and Beast Boy kissed but Robin does when Starfire does kisses Beast Boy and other characters in the episode instead of him.
 * This was probably because unlike Robin, Raven understands that the kiss was meant for Starfire to pick up his vocabulary skills and nothing romantic.

Running Gags
