Why do you like pokemon??!!
Beat Stormy Sea
It is in stormy sea. You'll need the TM Dive, you can get it from Wishcash at the pond.
40 floors
If Blue is basically the same as Red, then it's the Stormy Sea Dungeon, B40F. It's the Stormy Sea Dungeon Xludo73: it's the stormy sea dungeon at B40F but I recommend bringing your strongest Pokemon there since kyogre is powerfull!don't forget to bring the huge apples and reviver seeds! you can get them at the kecleon shop!
Spheal can be found in the Stormy Sea dungeon and its friend area is the Ice Floe Beach.
You can recruit water Pokemon like squirtle and totodile in waterfall pond and stormy sea after you beat rayquyaza
You find Kyogre at Stormy Sea on 40F.
