Victoria, a horse villager from Animal Crossing, is standing on an abstract background. She is wearing her usual racing cap and a "1" shirt (interpreted as a crop-top) and a white adult diaper with a simple off-pink designs. The diaper is soaked, but Victoria's body language still reads the need to urinate. She says in speech bubbles, "Hey, don't you happen to have a spare?..", "I, like, really need to use the restroom." A small bubble on the bottom continues the phrase: "...again." Her face is worried and she is trembling, trying her best to hold it.
Next to the main image there are a few rough sketches: Isabelle presenting Victoria with a bunch of diapers and a paper that reads "Notice: Victoria had too many accidents and must wear diapers." followed by a signature. Isabelle's face reads it's nothing personal, but it has to be done. Victoria looks astounded and embarrassed.
Other sketch shows Victoria drinking from a water bottle, already in a diaper: 6 more empty water bottles are lying around her.
Last sketch shows Victoria, Kid Cat and Amelia at a low start, seemingly about to start a running race. Victoria looks in front of her with a determined face, while the other two beside her are eyeing the thick diaper, visually protruding from Victoria's silhouette.
Victoria is a literal racehorse, having the need to stay well-hydrated and suffering a set of related consequences. Thankfully, the solution is very simple.
