Plot
Chad and the family pack to go to a resort and spa at Kingsville, Texas. Sumo, Jeff, and Amy (who had moved back as she missed Clarence) later tag along with the trip as they had gotten their parents' permission. The gang pulls over, having to find the car out of fuel, after Chad had not stopped at a gas station. They find themselves outside a town called Beach City. As they enter the Big Donut, they meet Greg Universe.

Greg later brings them to the beach house, where they meet the Crystal Gems. Steven shows Clarence his mother's room and shares his adventures with the Gems. Sadie brings Amy to her home and they talk about themselves. As time passes, Clarence and Steven become best friends later on. With Jeff, he gets information from Garnet about their history for "personal reasons". With Sumo, Amethyst takes him on a mission. Both Chad and Greg return back with a gas canister for the car, having to find the engine killed after all that driving.

Meanwhile with Sadie, she had told Amy about all her old activities from being ballerina and as a softball player. Amy begins telling Sadie about her rough time after moving away from Aberdale, to which Sadie becomes concern. Pearl and Mary return from seeing a matinee, but Mary was less than pleased. Amethyst and Sumo return from their mission, and Sumo brings back a living Centipeetle, but it gets loose around the town after showing Clarence and Jeff. Fortunately, they catch it in time and destroy it.

Unfortunately, the Centipeetle had destroyed half the town, leading them to return to Aberdale after being banned. Sadie gives Amy her "Haven't You Noticed (I'm A Star)" CD as to remember her. After Steven and Clarence say their goodbyes, he shows him his face plastered on every photo covering everyone but Steven, including portrait with his face drawn on it. Steven, weirded out from Clarence's "memento", ends their friendship. Before he got into the car later apologizes to Clarence for ending their friendship, but Clarence doesn't except his apology after he hurt his feelings. They later sit at the beach and talk about their differences. After their conversation, they respect their opinions and agree to remember each other. After returning home, Jeff had gotten a B- on his report, and Clarence pretends that he is still mad and over Steven, but secretly misses him.

Development
A long time fan of Clarence, Xavier Shaquille, had the idea since late 2014. The first draft was with Clarence showing a newspaper with the headline of the Crystal Gems to Jeff and Sumo, followed by suggesting they go to Beach City; and the boys travel there on a handmade boat, despite his mother Mary declining his wish. The second draft was with the story opening with Clarence reviving his farting cactus comic; which was introduced in the Season 2 episode "Freedom Cactus"; only for him to end it afterwards. Arriving back home, Clarence is annoyed in living in a mundane life despite his imagination, in which Jeff decides that they go somewhere my themselves, to which Mary refuses until being talked into agreeing with it. Also, in the draft, Amy had returned to see Clarence again right before the boys take off. He would pitch the idea to the writers and producers of the show.

Estelle, Michaela Dietz, Deedee Magno-Hall, Tom Scharpling and Kate Micucci were brought in to voice their Steven Universe characters; Steven was voiced by Natalie Palamides due to his original voice actor Zach Callison due to his aging, currently unable to make Steven's voice akin to the original series.

For the episode's animation, and rest of the revival as a whole, the animation was provided by Sunmin Image Pictures; the animation company had previously animated Steven Universe: The Movie (2019). Color stylists Tiffany Ford and Juliana Park were in charge of giving the Wendles and their friends the color motifs of the Steven Universe franchise when entering Beach City.
