Titre original : The Problem with Paras
Having run out of medicine, Ash and his friends go to a shop in Mossgreen Village to get some healing potions. The shop's owner Cassandra wants her weak Paras to evolve into a Parasect so she can use Parasect's mushroom for a new kind of miracle potion. Ash, his friends, and Team Rocket all decide to help out Cassandra by training her Paras, hoping that it can evolve into Parasect. Paras finally evolves after beating Charmeleon in battle.
