tandemaus to maushold: trying to get 3 form
requires level 25 and leveling up from battle exp (rare candy does not work)
what has been tried/ what doesn't have an effect:
game version
character gender
last digit of trainer number
level up with low hp
level up with status condition
level up with 3 moves
level up with all multi-hit moves
level up and then ko'd in battle
level up by capturing a pokemon
evolving by itself
evolving with a full party
evolving with other tandemaus
evolving at an odd/even level
placement in party
evolving with certain party members (dunsparce, scovillain, meowth)
evolving with more special attack than attack (and vice-versa)
weather
dominate gender in party
evolving with or without a held item
turns taken in battle
natures that have yielded 4-form
relaxed, timid, sassy, jolly, mild, hardy, quirky, brave
natures that have yielded 3-form
quiet
