The Jugglers were NPCs in Nimbus Park. When interacted with, they would juggle pieces of the Mime. On December 19th, 2011, a LEGO moderator named Shival hosted a party for players in Nexus Tower spawning various NPCs and creatures, including both jugglers. While they offered to show off some juggling when approached, they would not play the animation when interacted with, likely because the Nimbus Park scripting was not loaded.
