You can't.
In Pokemon Mystery blue Dungeon, after you beat Rayquaza, you should be able to go to a dungeon called solar cave. There you will find the HMS surf, dive, and waterfall. In sublevels 10-20 you should find a few Chimechos. I have one Chimecho
Spheal can be found in the Stormy Sea dungeon and its friend area is the Ice Floe Beach.
find it in a dungeon
Use Rock Smash
Whiscash Pond is not in Pokemon Mystery Dungeon: Explorers of Time/Darkness. It is in Explorers: Red/Blue Rescue Team though.
No... there is no regigigas in Pokemon Mystery Dungeon Blue Rescue Team. Do you know why? If not... I will tell you. This is because regigigas is one of those new Pokemon from the sinnoh region which was not invented during the time of Pokemon Mystery Dungeon Blue Rescue Team. However, I believe you can find a regigigas in Pokemon Mystery Dungeon Explorers of Time, Darkness, and Sky.
Just go to UPokeCenter.com and find the wonder mail generator. for red and blue it is regular mystery dungeon, for darkness, time, and sky it's mystery dungeon 2
