Vivian has a tube,and she wants to get another tube, but she can't reach it, so she uses her long tube to get the other tubes down. That's when a bunch of tubes come falling down. So then, Cece makes a tube shaker, out of a paper towel roll (it's a tube), and rice. Vivian and Brandon make tube tubas. And Tony gives Dane a slide whistle. They get their tube instruments together and sing a tubey song to celebrate Tubes Day. They make tube suits and hats before playing another song; this one is about living in a tubular world. Finally, they play out a story about Tube Town.
