you have to go to a special event, but this event will probably take a long time to come why talk to the hackers of DP
you can not catch celebi in Pokemon platinum
You can't, Celebi is obtainable by events. The only way you can find a Celebi in Pokemon Platinum is by cheating.
trade it from someone who did cheat that way you didn't cheat
The only way to get Celebi on Pokemon Pearl without AR cheats is via event distributions. However these events are no longer being held or supported for Pokemon Diamond, Pearl and Platinum.
use the Pokemon modifier
celebi is onlyobtainable throw Nintendo events
Not without cheating
Yes you can at the Solaceon Ruins. Battle/Catch 99 Unknown and the 100th Pokemon you see will be Celebi.
I don't know for certain, but I believe there was an event for Celebi a while back. That was the only legitimate way to get Celebi in Platinum without trading it from another game. The only other way to get it is to use an action replay code (or gameshark). That's how I did it! XD
I have one in Pokemon platinum one in Pokemon diamond and one in Pokemon crystal
You need the event to find celebi without cheating.
there was an event for it which is now over. you can still get it by cheating :)
