I don't know if you are looking for ideas to put in the game but while I was looking at so pokedex entries I saw that Pidgeotto's entry says it claims a large area as its territory and if anyone enters its area it will punish it with out mercy and I thought that maybe Misty or Pikachu could run into a Pidgeotto's territory and get caught and punished resulting in ash having to find and save them giving you a chance to get a pidgeotto
