Pat finds his old childhood bear, Billy, in the attic. He then allows Julian to take Billy to school where he swaps it with Charlie's magnifying glass.
Charlie then loses Billy, but Katy and Tom find him again and swap him with Sarah Gilbertson for a rope. Sarah then loses the bear, but it is then found by Alf Thompson. The Bear then gets moved again and is found by Ted Glen.
Pat and Julian travel to each of the places Billy had been to get him back. He is eventually found in the Station cafe, where Ted has given him to Nikhil.
