# Near the top of the script section Pokemon_MultipleForms, find this method and rearrange it as follows:

  def form=(value)
    @form=value
    MultipleForms.call("onSetForm",self,value)
    self.calcStats
    pbSeenForm(self)
  end

# Rewrite the following two procedures as follows:

MultipleForms.register(:FURFROU,{
"getForm"=>proc{|pokemon|
   if !pokemon.formTime || pbGetTimeNow.to_i>pokemon.formTime.to_i+60*60*24*5 # 5 days
     next 0
   end
   next
},

MultipleForms.register(:HOOPA,{
"getForm"=>proc{|pokemon|
   if !pokemon.formTime || pbGetTimeNow.to_i>pokemon.formTime.to_i+60*60*24*3 # 3 days
     next 0
   end
   next
},

# That's all you need to do.
