Pokemon Mystery Dungeon: Red Rescue Team Questions

How do you unlock wish cave? Mainly, how do you unlock the part where Medicham and Ekans are talking? I forgot how I did it last time...

Once you have the Lati@s duo and Sky Blue Plains Friend Area, you need to head to Whiscash's pond and look for Medicham and Ekans from Team Meanies. Talk
To them, then complete optional missions, then go talk to them again. Complete more missions, then only Ekans will be left, head to the Pelipper Bulletin Board and look for a rescue request from Medicham to unlock this dungeon.

To enter you will need HM Surf, money will be reduced to 0, level will be temporarily reduced to 1 and you will be forced to save before entering.

This is another 99 Floor dungeon where your level will be set back to 1. Something to make the entire dungeon easier on you is giving your leader the Tight Belt and spending some time leveling up, especially on the Skarmory floors. If you are just here for Medicham (I think it's on the 20th floor), make sure to do some leveling on your way up so you can't get yourself into too much trouble. Some Pokemon like Togepi can only be found here also, so you will need to probably come back to recruit some.

If you lose your Wish Stone, you can find another on the 50th Floor. If, when you reach the 99th Floor, you have the Wish Stone on you, Jirachi can grant you a wish. If you get him to grant you a wish, you can still come back to recruit him. When you are ready, defeat Jirachi and he will join you with his 99.9% recruit rate (make sure leader gets final blow, etc.). Some of you won't want to brave this dungeon more than once to get wishes, and can just recruit him on the first attempt and never have to worry about scaling all 99 Floors again.

For Recruiting purposes: Jirachi is lvl 40 when recruited.
