The Great Gokulin Repelling Strategy!! : Season 7 Episode 25

Facing another in a long string of Gulpin invasions that had cost them years worth of food stores, a small village decides to call in a Gulpin expert. Though the professor's high-tech answer to the Gulpin question at first drives them back, these Pokémon soon regroup and continue their charge toward the food storehouse at the center of the village. Fortunately, Ash and friends chance across this troubled community with impeccable timing. If only they and their Pokémon prove strong enough to hold back droves of tenacious Gulpin.
