Wait until you get mail about a
Really hard dungeon starting at
Lv.1. Then go to wishcash pond
And you will find medicham and
Ekans talking about a dungeon
That grants wishes.they will leave
After you listen, go do an easy
Dungeon like tiny woods.go back
After you pass it and they will be
Talking again.keep doing the
Same thing until you find ekans
Alone.do tiny woods again and go
To the bulliten board.you will find
Ekans looking at it.there will be
One saying medicham needs
Help.accept it and you will have
Wish cave.rescue her and she will
Give you the wish stone.she will
Be at floor 20.good luck its pretty
Hard in there!
