How do you recruit mew in Pokemon mystery dungeon blue?

how to recruit mew

-go to relic ruins ( i think) by talking to shiftry after beating rayquaza

- get all three regi parts ( on 15 bf, 25 bf, and 35bf)

-after you beat registeal on 35 bf, you will get a "music box" - do not use the item or it will break.

-wander around the 99 floor dungeon (relic ruins is 99 floors) until you see in the message screen about mew doing something. walk around the dungeon and start killing (mew can appear anywhere from 35bf - 99bf, but it should appear on every floor as well, so you can just walk the entire floor, but that kills your belly and mew sometimes is not on a floor)

-make sure you have a friend bow or something-mew doesnt have that high of a recruit chance, and comes with his own friend area
