you can evolve it by using double hit to level it up. it learns double hit on level 32. (or was it 33?)
Aipom does not evolve by level in Pokemon HeartGold. Aipom evolves when it levels up while knowing the move Double Hit, which it can learn at level 32. This makes level 33 the earliest level at which an aipom can evolve.
Level Aipom up with Double Hit (learnt at Lv 32)
Aipom will evolve into ambipom when leveled up while knowing the move Double Hit. Aipom learn Double Hit at level 32, so the earliest level it can be evolved into an ambipom is level 33.
actually it evolves when it learns ancient power usually at lv.33
Aipom does not evolve in emerald
aipom does not evolve inpokemon emerald
Aipom evolves at level 32, teach it the move it want's to learn then it will evolve.
You can find an aipom when you headbutt trees, and you can evolve it into an ambipom after teaching it double hit, which can be learned naturally at level 32
aipom has to learn double hit to evolve into ambipom
at level 32, only because it learns double-hit. if you don't let aipom learn this move. it won't evolve.
Aipom has to learn Double Hit then level it up again. (Aipom learns Double Hit at level 32)
Aipom must learn double hit at level 32 then it will evolve in to Ambipom. By Lachlan Mcleod
