At the Pokémon Center on route to Driftveil City, Ash and co. meet Robert, a Pokémon photographer, who wanted to see a sight no one has ever seen. No one that is except his grandfather: All four season forms of Sawsbuck gathered in the same place at the same time. Though Cilan explained that it was impossible for this to happen, Robert explained that it did happen because his grandfather took it. That was his photo. Can Ash and friends be able to help Robert find the Sawsbucks by tracking the Deerlings?
