Bob gets a call from Mr Bentley who wants him to renovate the museum's annexe, where Mr Ellis plans to exhibit the work of local artists. The roof and floor must match the rest of the museum, but JJ doesn't have anything suitable in stock. He suggests that Bob sees if the materials from the demolished house are still at the recycling center. But Spud has helped himself to the old floorboards to build a sculpture for the exhibition. Bob loads Scoop up with the old tiles and returns to the museum. A disappointed Mr Bentley says they'll have to use new floorboards instead. Bob and Scoop take the rotten boards off to the dump, but on the way they pass Spud who is having problems with his sculpture as the pieces of wood are proving too long. Bob is delighted to find his floorboards and Spud is happy to swap them for the old bits of wood which Scoop is carrying. Wendy and Bob finish the restoration work at the annexe, and the exhibition is a great success.
