Mall-based. Fast-paced. Built for Philly suburbs families. Sloomoo MiniMoo Philadelphia, located inside the Plaza at King of Prussia Mall, is a smaller, more focused format than the full Sloomoo Institute, designed for 1.5-hour birthday parties on the second floor next to H&M.
Kids dive into the Sloomoo Slime Wall, hurl slime at the Sloomoo Slingshot, customize their own slime at the DIY Slime Bar from millions of combinations, and take home a Clay Creator Kit unique to the MiniMoo experience. The Sloomoo Slime Party covers a private party room rental, VIP guided tour, dedicated host, and a keepsake slime jar for every guest. Upgrade to the Ultimate Slime Party for a private slime-making class with two themed options: Sweets and Treats or Mythical Creatures.
Looking for the full Institute experience with Lake Sloomoo, Sloomoo Falls, and an ASMR Sound Bath? Those features are located at our other Sloomoo birthday party locations.
