Just as the gang enters the city, they notice a band of Smeargle running amok, painting every bare wall in site with their tails. Ash stated he thought the Pokémon were Smeargle, before confirming this with the Pokédex. Dexter quickly explains these Pokémon express themselves by painting and the color in their tail depends upon the Pokémon’s mood. Just then, the townsfolk appear in an angry mob, demanding the Smeargle stop this graffiti. Before the scene gets out of control, a famous artist appears to claim the three Smeargle. The man gives the townsfolk a blank check from the First Johto Bank to cover any costs of repair. A TV reporter enters and asks the old man if he is Jack Pollockson, and he confirms it. With more questions, Pollockson reveals his paintbrushes are the trio of Smeargle. The three go on to paint some of the townsfolk, including Ash and friends, and buildings in red, yellow and blue lines. Pollockson examines the Smeargle’s latest creation and says he is unsatisfied and that it has been a long time since they have painted anything of quality.
