About This Mod
If you’re a Hello Kitty fanatic like me, this CAS background is about to become your new obsession. It’s a full-on kawaii explosion, designed with bubblegum pink wallpaper and endless Hello Kitty plushies lining the back wall. Your Sim is basically living in Sanrio heaven, complete with a themed bed, a cutesy rug, and even a pink PC setup. Every detail screams cozy, girly, and unapologetically adorable. In addition to the Hello Kitty background, you also get a Kuromi and My Melody CAS Background. Note that you can only have one of the three backgrounds in your mods folder, so choose wisely! If you’re looking for more CAS background options for your gameplay, check out our article on Sims 4 CAS Background CC.
