Go to Slateport City and there is an event that has Capt. Stern being interviewed. you talk to him and you'll read something about thank you for the sub or something. you go into the dock and you'll see the sub being stolen. after that happens go to Lilycove and where the Wailmers are, you have to surf up from there until you see what looks like a cave. you'll end up seeing the warp panels, like the gym in saffron city in Pokemon yellow, red, blue, firered, and leafgreen, you got to test the panels to find where they take you. in team aqua's HQ you also get the master ball, so be on the look out for it. its in a room with 4 poke balls on the floor. two of those are either voltorb or electrode. but once you find a room where the sub is you face one of the grunts and then the sub leaves. once you leave the cave the wailmers should be gone.
use the wailmer pail.
Wailmer evolves into Wailord at level 40.
stand in front and use the wailmer pail at it,it wall say:the tree does not like the wailmer pail!the tree attacked!
You have to find it in the cave
beat the team aqua base
Evolve a Wailmer (Level 40)
To move the Sudowodo in Pokemon emerald you have to wet it with the Wailmer Pail and it will attack you. I suggest you try to catch it because it is a very good Pokemon. I think it will be a level 40
you can get wailmer everywhere in the water on emerald
surf nere the sky tower
Yes, you can. Though it's much easier and faster to catch a Wailmer by fishing.
You have to go through the hideout which is the cave slightly north of the wailmer. In the hideout you have to beat the admin at the end and see the submarine sail away, you can also get a masterball in there too
get the wailmer pail from the flower store and water it!
