It is possible to become stranded on the Meister's island after trading with him. If the traded Finneon was the only member of the player's party that could learn Surf, and no Pokémon in the player's party have Surf, Fly, or Teleport, the only way to leave would be to level up "Foppa" until it evolves and can learn Surf as a Gyarados, by fishing for battles or through Rare Candies. As it is possible to progress through the game fully without picking up any fishing rods, yet still have Finneon (through a trade), and since Rare Candies can be used up, players can become stranded on the island until they restart their game, or use a walk through walls cheat code to leave.
