Kant Dance hangs out in the amphitheater's stands, where she constantly plays air guitar. If players interact with Kant, she tells them how much she loves Red Blocks and how the concert area needs some rock stars to play the Concert Instruments.
Prior to the Nexus Jawbox update, Kant Dance wore Purple Pants. Since many other NPC clothes were turned white with this update, this is likely a glitch, but it was never corrected before LEGO Universe was announced to close.
Kant Dance's name is a play on the words "can't dance".
Kant Dance is the only lady in the audience of Red Blocks whom Johnny Thunder does not try to offer a chance to meet in person.
