Plot
While clearing trash from Fixham Beach, Lofty collects all of the driftwood he can find. Scoop is baffled that Lofty thinks the driftwood is beautiful and tries to throw it all away. When Muck hauls the debris to the dump, Lofty spots a prize piece of wood, and grabs it, causing the trash to fall back into the water! With creative problem-solving and teamwork, Bob uses the driftwood to create a floating barrier in order to collect the flotsam and jetsam. Later they use the driftwood to decorate the path to the beach. Even Scoop is impressed.
