I just turned all my fingers into cats!
The episode begins with Steven and Greg, cleaning Mayor Dewey's Van and play fighting with the water hoses. After they finish cleaning, a cat holding a hose in its mouth starts spraying Steven and Greg. The cat reveals itself to be Amethyst.
Steven asks Amethyst if he could shapeshift like her as they walk to the Crystal Temple. When they arrive Amethyst shows off her shapeshifting powers, and Pearl tells Amethyst that just because she can shapeshift doesn't mean she should. Steven asks Pearl if she could shapeshift. She answers that all Gems can, and Amethyst interrupts by shapeshifting into Pearl and mocking her.
Pearl leaves, and Steven asks Amethyst how to shapeshift. Amethyst explains her methods of shapeshifting, and Steven attempts to turn into a cat. He manages to transform one of his fingers into a meowing cat head. Amethyst then tells Steven to show it to his dad, and Steven runs around showing off his cat finger. Steven meets Greg at It's a Wash and shows him his morphed finger, and Greg, frightened, sprays the cat with water from a bottle.
Steven walks to the Big Donut and shows Sadie and Lars. Sadie is amused and pets the cat, making it purr. When Lars tries to pet it however, it bites him. Sadie says it was probably playing, and Steven realizes it doesn't have any friends, so he transforms four more fingers into cats so the original finger won't be lonely. At the fry shop, Steven demands fry bits from Peedee, which he then feeds to the cat fingers. Peedee's older brother, Ronaldo, notices and takes a picture of the cats for his blog, "Keep Beach City Weird". In the process, Steven turns the fingers on his other hand into cats. He tries to pick up the phone and look at the picture, but the cat fingers screech at him for having their faces smashed into the phone.Steven returns to the Crystal Temple and asks Amethyst for help returning his fingers to normal, as the Gems are leaving to fight a "living island". Pearl insists that they stay to help Steven, but Garnet says they can't because the mission is urgent. Pearl blames Amethyst for this; Amethyst replies, "that's fair." Pearl tells Steven to stay calm as they leave.
Back at the Temple, Steven tries to revert his fingers back to normal. Unfortunately, his efforts exacerbate his condition and Steven begins to sprout writhing, meowing cat heads all over his body at a cancerous rate, and he runs to the only person who may be able to help: Greg.
By the time Steven reaches Greg, the cats have almost completely overtaken Steven's body. Greg, surprised by his appearance sprays Steven with the hose, which allows Steven's face to emerge as he begs his father for help. Greg reaches toward his son in an effort to comfort him, but one of the cat fingers bite him. Steven begins to contemplate the full extent of his condition, then suddenly realizes the only thing that can stop the cats is water. He tells Greg to spray him with the hose, but it does not produce enough water to remove the cats. Steven begs Greg to use the car wash, but Greg insists that the super wash is too dangerous. Greg finally relents and heads into the car wash as the cats almost completely consume Steven's body. Steven struggles to crawl into the car wash, and is blasted by numerous jets of soap and water.
The wash successfully clears the cats from Steven's body. Before they can celebrate, they find that one cat finger is still remaining, but Greg immediately sprays it with a hose.
The Crystal Gems return the next day, and Pearl rushes to ask if Steven is okay. She then begins to lecture Steven about him listening to her instead of Amethyst, to which Amethyst agrees. Garnet interjects that the alternative lesson they all learned, was to place more faith in Steven. The episode concludes with Steven dropping several cheesy cat puns, much to the annoyance of the other Crystal Gems.
