Quick. Hands-on. Built for Boston celebrations. Sloomoo MiniMoo at Faneuil Hall Marketplace is one of the best birthday party venues in Boston for parents wanting a smaller, faster-paced format than the full Sloomoo Institute, designed for 1.5-hour birthday parties inside the South Market Building. 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? Compare all Sloomoo birthday party locations. Get the full rundown on hours, directions, and what to expect at the Sloomoo Boston location.
