I dont know how many people noticed it but when we enter south aventurine for the first time, just before battling fern on route 1, while moving towards route 1 a pokemon/thing is shown to flee from us.. I was wondering if it was an event pokemon or something cuz i havent been able to find any such pokemon on route 1 or anywhere for that matter.. and we dont see it in the game either.. or maybe i missed it.. not sure.. anybody knows anything about this??
