King of Prussia Mall is about to get slimy, writes Sharon Edelson for Forbes.
The Sloomoo Institute, a wildly popular interactive slime museum with flagship locations in New York, Atlanta, Chicago, Houston, and Los Angeles, is opening a scaled-down “MiniMoo” at one of the nation’s largest shopping centers.
The new 3,000- to 4,000-square-foot space will combine retail with hands-on experiences, inviting visitors to knead, stretch, and swirl slime in a setting designed to spark creativity and calm. Co-founders Karen Robinovitz and Sara Schiller describe slime play as “cathartic,” pointing to research showing three-quarters of adults report improved mood and creativity after diving into the goo.
At King of Prussia, shoppers can expect colorful slime, quirky merchandise, and a retail space shaped around the brand’s mascot, Sloomoo—a shape-shifting character that embodies the product itself. Visitors also receive a personalized “Sloomoo slime name,” inspired by an online trend that replaces vowels with “oo.”
Beyond the mall, Sloomoo is planning two larger locations for 2026 and an expanded merchandise push that includes slime charms, apparel, and themed boxes. The brand has already attracted celebrity fans such as Serena Williams and Ciara, thanks to its mix of social-media buzz and word-of-mouth marketing.
