I'm afraid you cannot get a Celebi in Pokemon HeartGold, unless you use a Action Replay. The only Celebi legal, I think, is the Nintendo Event that has passed. If you do have the Celebi in your GameBoy Pokemon Cartridge, then you can migrate it to Pal Park, then trade from Pearl/Diamond to HeartGold/SoulSilver.
Get the celebi event.
No, unless you want to use the Action Replay for the Event.
You don't. He's not there. Only in HeartGold and SoulSilver with the Celebi event.
You can get a Spiky-eared Pichu in Pokémon HeartGold and SoulSilver if you get the movie-event Pikachu-colored Pichu and bring it to Celebi's Shrine in Ilex Forest in HeartGold or SoulSilver.
you get celebi in an event at 2005
A celebi event has already passed. The celebi event for HeartGold was available in Japan at the release of the game. There isn't an event for celebi going on right now.
You can find Celebi with the special event.
You do not get Celebi anywhere in HeartGold. The only ways you can get a Celebi is by downloading an available Nintendo event where it is offered however there wouldn't be anymore events for HeartGold or you can trade with someone else who was able to get a Celebi at an event.
The Celebi event for HeartGold and SoulSilver has already came and went. It started on February 21, 2011 but it ended on March 7, 2011. There is no chance of the Celebi event download for HeartGold and SoulSilver repeating so the only way you can get the event Celebi is by trading for it.
you can only get celebi in an event or pal park.
Well, Celebi is a Pokemon in a event, so you need to wait for the event.
You can only find celebi in the special event.
You need to have the Celebi event. it is over. sorry
you can't! you have to get the special event celebi or use AR
