Celebi glitch (party method)
Requirements
- The player must have beaten the Elite four.
- The player must have a box in Bill's PC that isn't full.
- The player must have a Sneasel that knows Beat Up as its third move (Sneasel learns Beat Up at level 57).
Procedure
1. Clone Sneasel correctly four times.
2. Clone Sneasel incorrectly one time and get a bad clone.
3. Put the original Sneasel in the first slot of the party, followed by the four good clones and the bad clone.
4. Go to the Daycare and ask the man, or woman, to raise your bad clone. Then, take it right back.
5. Now put the bad clone at the top of your party.
6. Go to the PC in the daycare and enter Bill's PC.
7. Chose "Move PKMN w/o mail", and move any Pokémon from a PC box to the top of your party but be warned, that Pokemon will vanish. So let if be a useless Rattata NOT a rare or legendary Pokemon like Mewtwo.
8. Turn off the PC and go back to the Daycare man. Ask him to raise the bad clone, which should now be the second slot of your party. This time, do NOT take it back yet, and go back to the PC.
9. Deposit Rattata and the four good clones, and turn of the PC.
10. Go back to the Daycare man and take back the bad clone. Then, ask the man to raise your Sneasel. At this point however, Sneasel's name will probably have changed to SEL.
11. Take back Sneasel from the Daycare, and it should now be a Celebi. However, this Celebi will not appear in your Pok�dex and might be at a very high level.
12. If you look at the PC box where you deposited Rattata and the four good clones, you will notice that the third and fourth clones' species, viewable from the first page of stats, have changed (but you should still see the Sneasel sprite). When you withdraw these clones and put them in the Daycare, they will transform.

Notes
For some reason, in Crystal, if you look at the stats of the second clone in the PC box, the game might freeze and glitch.
This glitch can also be used to get any Pokémon in the game! The way this glitch works is the third move of the Sneasel we used was Beat Up. On the HEX list Beat up has a HEX of FB, Celebi is in the same HEX slot. So if you changed the beat up attack to say the attack "Detect", Which has a HEX of C5, then the Pokémon that has a hex of C5, which is Umbreon by the way, would be the end result. Sneasel does not need to be used in this glitch, Sneasel is only used because it is the only Pokemon to learn the beat up attack. So that is how you get any Pokémon you want.
