King of the Forbidden Forest! Fushigibana!! : Season 7 Episode 33

May is captured by a Skarmory, and Ash and friends quickly give chase, only to find their path blocked by a huge barrier and two mysterious men who tell them they cannot pass into the forbidden land beyond. When they explain about their missing companion, the men order them to wait while they counsel with their village elder. When they hear a foreboding legend of dangerous Grass Pokémon beyond the wall, however, Ash and friends decide to sneak in to help May with or without the village elder's permission.
