Actually you can find Aipom in Pokemon Platinum. First you must put honey on the honey tree wait until half day and play it and go into the honey tree you putted honey and just keep doing it until you see Aipom.
MY NAME IS EVAN SO DO IT
go to mt. silver and headbut trees you may also find aipoms there.
Honey Trees
It's Aipom, and you can only catch Aipoms on Honey Trees in Groups 1&2.
get a munchlax and evolve it you get munchlaxes at the honey trees
You will find Aipoms in trees in Route 29 to 33 and Route 42 to 46. They are uncommon and they appear anytime. So it won't take very long to find one.
You can put honey on trees and check them the next day to see if aipom is there, (you have 2 be really lucky) or you can find them at: .route 204 .Eterna forest .route 205 .Route 211
use honey on those trees and check on it a couple of hours later
bidoof and bibarel can cut trees
A good way you can do it is get an aipom from the honey tree, then evolve it into an ambipom.either evolve the aipom or go to pastoria city at a certain day ( idk exactly when ) and theres a clown named lee in the Pokemon center, he has an ambipom lv 50Another way to see one would be to battle Ace Trainer Blake on Route 216 who is just before the cave.you can't see ambipom but you can catch aipoms by slathering honey on trees and evolve them
teach a Pokemon headbutt and use it on small trees teach a Pokemon headbutt and use it on small trees
