The Pack are working at Cronk station. Jack and Alfie are taken there by Percy. The conditions are very muddy, so everyone must be careful to prevent any dangerous situations from occurring. Byron's job is to dig out a trench. Once finished, he is sad that no-one seems to have taken any notice of his hard work. Meanwhile, Max & Monty are racing through puddles, splashing dirt all over everyone! The pair's silliness ends them running straight over a water supply. It is situated by Alfie, who is caused to start sinking into the now softened ground, due the gushing water. Byron the Bulldozer comes to try and rescue Alfie, but will he be able to?
