+1 , i agree with @Voldis4, the requirement to go hoenn is rising up a lvl 80 ratata , and fight a mini-boss of a six team of ratata.
Once completed the ratata will go to a trash can, none uses.
Can be really be a good change, to prepare players to go hoen and stuff...
i Don´t agree with this. Rising a ratata ot to lvl 80 is preaty easy, just by using a lvl up service or tarde witha friend to rise up at cerulean cave or whatever.
