The Twirlywoos find themselves in an office watching a very bored man who is entertaining himself by joining up some paperclips. When he's gone, Great BigHoo empties the whole box of paperclips on to the desk and starts joining them up too. It's not long before all of the Twirlywoos are joining up paperclips, and soon the room is filled with paperclip chains! Back on the Big Red Boat, the Twirlywoos learn more about joining up when they have to try and put the fruit tea machine back together.
