You're referring to Celebi, right? You can only get Celebi legally if you have a GS Ball from an event. It would be conferred to you by Kurt. Or, you can use a GameShark code. Either way, you would walk up to the Ilex Shrine and put the GS Ball into the Shrine by pressing A. Celebi would then pop out at Level 30. It isn't the strongest Legendary in the world, so be sure to bring some Level Balls if you bring a high-level Pokemon, or a Pokemon that is Level 35 or lower.
do something
You get Cut not in a town, but in the Ilex Forest. You get it after returning the Farfectch'd to its owner.
To get the Spiky-Eared Pichu you have to bring the special shiny Pichu from a Gamestop event to the Ilex Forest Shrine.
AnswerThere is no Pokemon inside that little house in Celestic Town. In fact, it is not a house but a small Shinto shrine which, in Japanese culture, houses the Shinto gods. As Celestic Town is in the very middle of Sinnoh and is surrounded by its legends, the shrine is most likely there to be dedicated to Uxie, Azelf, Mespirt, Dialga and Palkia (with the possibility of Giratina). Since there are ancient cave drawings of those Pokemon nearby, the shrine is most likely dedicated to them. Although the Ilex Forest shrine in Pokemon Gold, Silver and Crystal allowed you to capture Celebi, no Pokemon will appear around the Celestic Town shrine. It is simply there for aesthetic reasons.
The legendary forest Pokemon would most likely be Celebi. As well as being the time-travelling Pokemon, Celebi is also a protector of the forest - most notably Ilex Forest (in Pokemon Gold, Silver and Crystal). No other legendary Pokemon is linked to any forest in such a way, so Celebi would have to be it.
take the GS ball to the shrine in ilex forest

You must have the pichu from gamestop, and take it to the shrine in the ilex forest.
There is only one way to catch Celebi in Pokemon Crystal. In the Japanese version of Pokemon Crystal, players could use the Pokemon Mobile System to obtain a GS Ball as an event item. When used at the Ilex Forest shrine, it would start a battle with Celebi. No similar event was ever offered to players of the English version of the game.
how to pass in ilex forest
ilex forest
Only possible in the Japanese version of Crystal, and maybe the japanese version of Gold/Silver. Kurt gives it to you after some kind of event, and when it is put on the shrine in the Ilex Forest, celebi appears. It is common belief that it is INSIDE the pokeball, but in Crystal, celebi actually floats down from the sky to battle you and doesn't come from the GS ball.
That would be Celebi.
In Ilex Forest at Night time.
The note in the Ilex forest is towards the beginning of the forest. It is next to the Celebi shrine. You will most likely need cut to access the note and shrine, though.
Celebi is found in the Ilex forest near the 2nd Gym, at the shrine
In Ilex Forest. I can't remember where...
