Pokémon - Season 7 Episode 18

On their way back to Mauville City, Ash and friends travel through the Valley of Steel, home of many different kinds of Steel Pokémon and a potential shortcut to Mauville City and then Petalburg City. On their way through, they come across a Torkoal being attacked by several Steel Pokémon. After using Pikachu to scare the Pokémon away, the Fire-type hears a noise, also scaring it off. Later, having reunited with Torkoal, Ash and friends become determined to help Torkoal defeat the Steelix that lords over the valley. Will they succeed in cutting through the valley unharmed or will the angry Steel-type block their way?
