Nya, Nya, Nya (Prologue) is a Wiggledance! Live in Concert segment.
Greg notices that Captain Feathersword is holding juggling balls. Greg tells Captain it's not time to juggle since it's time for something else. Greg turns the audience to talk about something, but Captain Feathersword is juggling again. He turns to Captain Feathersword, who has hidden his balls, and asks if he was juggling. Captain denies it. Greg asks the audience and they affirm he is juggling. Greg takes the balls from the Captain and tells him to stand very still. He then talks to the audience about what's coming up, but Captain Feathersword is now dancing. The audience tell Greg that; Greg turns but Captain is standing still now. Greg asks Captain if he was dancing, but he denies it again. Greg asks the audience and they say yes. Greg tells Captain Feathersword no more juggling and dancing; just stay right there. But as soon as Greg turns to the audience again, Captain Feathersword runs off, and returns riding a unicycle. He loses control and runs into the backdrop. Greg tells him if he's okay. Captain says he's okay but what about his bike? Anthony says it must be broken since it only has one wheel. He and Greg leave to get it fixed. Meanwhile, Captain Feathersword shows the audience about a special new dance called, "Nya, Nya, Nya".
