On the northeast shore of Undella Bay, you can use your Dowsing MCHN to find a hidden Heart Scale. Neat. There's also a Draco Plate further north of that, which boosts the power of the holder's Dragon-type attacks by 20%. Now hit the sea and get ready to fight a whole ton of Water-type-using Trainers!

The Swimmer ♂ right near the Draco Plate has a Mantyke L39 on his team. Just north of him is a Swimmer ♀ with an Alomomola L39. There's a cave right past her, but it's blocked off by a guy and his pack of Roggenrola. You can actually find Seel, Tynamo, and Golduck if you run around in there, but I'll cover that area later, as you'll be back. It's the Seaside Cave.

To the east of the Swimmer ♂ is a Swimmer ♀, and she uses a Spheal L38 and a Wailmer L38. Further east leads to a dead end, with a suspicious black hole in the water. What's that for? That's for where you can use Dive to dive underwater in, but you won't be able to get the HM for Dive until after you've beaten the game.

Diving to be Rich!

Just because you don't get HM06 (Dive) until after you've beaten the game doesn't mean you can't go diving, even without trading! Two Pokemon you can find in the area — Wailmer and Seel (found in the Seaside Cave north of Undella Bay) — both learn Dive naturally at level 41 in their unevolved state (or later in their evolved state).

If you feel like making a fortune, train one up to level 41 (Everstones are helpful to keep them from evolving) so it learns Dive, then use it on the dark blue patch of water. You'll be able to explore the Abyssal Ruins, which holds a whole ton of the Plate items on the first floor, which raise the power of the respective type's attacks by 20%, as well as a whole ton of Relic Loot, which can be sold to the Black Belt in the westernmost house in Undella Town for a fortune. If you gather up all of the loot (which may take awhile and several attempts), you can sell it to him for over $2,000,000, which should be more than enough money to buy whatever you want.

I'll cover the Abyssal Ruins more in-depth in the post-game section of the walkthrough, but in my initial testing, it seems to at least have the same layout as in the original Black / White Abyssal Ruins. If you're feeling adventurous, check out the Abyssal Ruins section of the Black / White Walkthrough, which should help out a bit (even though it's for the original games).

Go on west and you should find a Swimmer ♂ that uses a Basculin L39. Keep going west until you find the shore again, then head a little south and you'll find some shallow water you can land at. There's an Ace Trainer there with a Pelipper L40 and a Starmie L40. She's right near a Splash Plate, which is another one of the Plate items that boosts a Pokemon's Water-type attacks by 20%.

Head east from her and you'll find yet another Swimmer ♂. This one uses a Sealeo L39. He's the last one you have to fight, though, and pretty much the only thing left to do here.

At this point, you can either head south of Undella Town to Route 14 if you haven't done so already to pick up some extra loot, or you can just go ahead and proceed to Route 13 to the north of Undella Town to continue on your adventure. The choice is yours!
