Emerging from the Mountain you find yourself practically in the middle of town, but before you rush off to explore head east and south around the narrow path that runs below where you entered to get the Berry Juice from the Treasure Ball there, and then make sure your Dowser is turned on as there are a few hidden items to be had here!
North of the entrance by the payloader is a Shiny Stone, while on the beach is a Heart Scale, and two Pearls. After you grab the three hidden items, Surf out into the water and troll back and forth to capture the available Pokemon below.
Dex No. | Name | Type | Location |
104 | Basculin | Water | Surfing / Water Holes |
180 | Frillish | Water/Ghost | Surfing |
181 | Jellicent | Water/Ghost | Water Holes |
239 | Starmie | Water/Psychic | Water Holes |
238 | Staryu | Water | Surfing / Water Holes |
After you obtain all five of the above that will complete the Habitat List for Undella Town, as well as the Habitat Listing for Route 4's Surf section and the Surf sections for Virbank City and Virbank Complex. Nicely done you!
On the Town
With the Surf collecting completed, heading for the Pokemon Center to heal up is probably a good idea... After you heal up chat up the people in the Center to receive a Prism Scale, and the Funfest Mission “Shocking Shopping” from the man-in-black in the corner when you say you would pay $1000 for a berry.
After you exit the Pokemon Center, head towards the nearby gate and Hugh will appear for the traditional Rivals Battle to determine who is the best – and that would be you mates!
Hugh opens the battle with his Level 39 Unfezant, followed by his Level 41 Serperior, and then his Level 39 Simisear. You can easily deal with the first two by using your battler, but for Simisear you should change to your Water Pokemon to make quick work of it! Hugh ends up paying you $4100 - sweet! But having to admit you are better than him? Priceless.
Of course he cannot just stop there, he has to go on and tell you about all of your responsibilities... Really Hugh? Really?!
The Marine Tube is closed right now but there is a vending machine in the lobby if you need to replace your beverages. The house to the right of the Tube Station belongs to Caitlin, one of the Elite Four (you should remember that).

Load your Dowser and follow the beach east and north crossing over into Undella Bay to grab a Heart Scale, and then head all the way north to grab the Draco Plate from the Treasure Ball there.
Dex No. | Name | Type | Location |
180 | Frillish | Water/Ghost | Surfing |
181 | Jellicent | Water/Ghost | Water Holes but not in Winter |
234 | Mantine | Water/Flying | Water Holes but not in Winter |
233 | Mantyke | Water/Flying | Surfing but not in Winter |
235 | Remoraid | Water | Surfing |
244 | Sealeo | Ice/Water | Water Holes in Winter Only |
243 | Spheal | Ice/Water | Surfing in Winter Only |
240 | Wailmer | Water | Water Holes |
241 | Wailord | Water | Water Holes |
245 | Walrein | Ice/Water | Water Holes in Winter Only |
You should already have collected a Frillish and Jellicent, so that means you need to capture pretty much all of the rest - bearing in mind that many of them can only be caught in Winter while others cannot be caught in Winter, so this is certainly a carpe diem sort of thing.
Heading out into the bay there are sand bars with trainers and items – head east to the first sand bar and grab the Splash Plate from the Treasure Ball, and then have a trainer battle!
Ace Trainer Summer has a Level 40 Pelipper and a Level 40 Starmie, and pays $2400.
Swimmer Matt has a Level 39 Mantyke and pays $624.
Swimmer Arissa has a Level 39 Alomomola and pays $624.
Swimmer Mitzi has a Level 38 Spheal and a Level 38 Wailmer and pays $608.
Swimmer Bart has a Level 39 Basculin and pays $624.
Swimmer Tim has a Level 39 Sealeo and pays $624.
The dark spots you see in the water are there for when you have the HM for Dive, which sadly we do not yet have... Soon though.
To the north of the area is a small beach with the entrance to Seaside Cave but the way in here is blocked at the moment so ignore that and then head back to town.
Head through the gate in the center of town and exit onto Route 13, to find a trainer waiting for you.
Black Belt Wesley has a Level 41 Gurdurr and pays you $1312.
Heading west up the stairs and onto the grass will take you to the next trainer.
Battle Girl Alize has a Level 41 Scraffy and pays you $1312.

Check your Dex to see which of the above you do not have, and then go get 'em!
After you have collected the Pokemon that you were missing, use your Dowser to grab a Zinc, a Heart Scale, Big Pearl, and a Pearl.
Using Cut on the tree west and then south of the first patch you can get a Max Repel from a Treasure Ball. In the area up the stairs just past the first patch (you have to use Strength to move the boulder) you can get a Red Shard from a Treasure Ball. On the beach below the first area is a Treasure Ball with an Ultra Ball.
In the surf past the first patch is Ace Trainer Miguel who has a Level 41 Delcatty and a Level 41 Eelektrik, and pays $2460.
Fisherman Leroy has a Level 40 Vaporeon and pays $1280.
Enter the water, heading north to the green island and grab the Treasure Ball in the center that contains a Luxury Ball. Continue north and east to the sand bar where there is a Treasure Ball which contains TM29 Psychic.
Fisherman Vince is at the other end of the bar, with his Level 40 Golduck, and he pays you $1280 for the lesson in battle with you.
Head west to the beach and battle Parasol Lady Laura has a Level 40 Castform and pays $1280.
Fisherman Damon has a Level 39 Basculin and a Level 39 Staryu and pays you $1248.
Fisherman Jones has a Level 40 Alomomola and pays $1280.
A trainer on the shore to the west gifts you a Red Flute, and tells you that he is there every day looking for treasure so you should check back with him each day.
Inside the nearby house is a pair of trainers you can chat up. Backtrack to the sand spit and continue north, heading up the stairs and then head south across the bridge to have another battle.
Ace Trainer Angi has a Level 41 Lopunny and a Level 41 Lampent, and pays you $2460.
On the bluff to the south is a Treasure Ball with a Star Piece in it, so be sure to grab that.
At this point you should backtrack to the stairs and head north, where you will find a pair of trees to cut, beyond which is your first proper Legendary Pokemon – Cobalion!
First thing you need to do BEFORE you cut the trees is save your game. Once you have saved your game, go ahead and cut a tree and head in to confront Cobalion – the idea here is to capture NOT kill this Pokemon, so go easy, because even weakened this guy is no easy catch. Plan on burning through a large Number of Poke Balls or getting really lucky and nailing him quickly...
This first Legendary battle will drag on and on as you try to capture it that you will be very tempted to use your Master Ball... My advice? Don't do that.
This is NOT the Legendary you need to use that on. Basically this is a numbers game, so just keep chucking balls at it and if you fail to catch it and run out of balls, so what? Just re-load your save and take another go at it, because it really is a random Number game, and luck.
From a strategy point-of-view it seems that getting him into the red is really necessary, and that having a good supply of Ultra Balls is also a really good idea... I easily burned through between 20 and 50 Ultra Balls in the process of experimenting with catching it, and found that having it down to a small amount of red used the least Ultra Balls.
Once you have captured this beast you should head into the green area on the right - the entrance is just ahead on the right - and grab the Max Ether from the first Treasure Ball and the Blue Shard from the second.
Pokemon Ranger Dianne has a Level 39 Larvesta, Flareon, and Vibrava that appear in a triple-battle, and pays you $2340. Following your battle with her she gifts you a Sitrus Berry.
What happens if you don't catch it and you didn't save so you can't go back?
