Bob gets a call from the Harbor Master and finds out that the old wooden pier in the harbor has disappeared overnight! Using an old picture postcard of the harbor as a reference to rebuild the pier, Lofty has the job of lowering new wooden posts into the sand. Lofty gets the wrong idea, and thinks that if he gets his tires wet, they'll disappear like the pier! Bob sends him off to the Suppliers Yard by the coast road, but Lofty doesn't want to be anywhere near the sea, so he takes a different route and gets lost. At the harbor, Lofty hurries to finish. Dizzy drives out onto the new pier, but noticing the water is getting closer, Lofty swings round in fright and knocks some planks. Dizzy is stranded at the end, with a gap between her and the shore! Lofty hurries to repair the pier to save his friend. He concentrates so hard, he doesn't notice that the tide has come in and hes standing with his tires in the sea! Bob explains that his tires won't wash away - they're waterproof! Air Date: Apr 14, 2010
