Dendemille Town

In this town:

• Pokemon Center
• Move Deleter
• Move Reminder

Head to the right and the professor and Dexio will call you. They will talk about the region's legendary Pokemon. Trevor will also arrive shortly.

After that, enter the first house to the right. Here, you'll find the Move Deleter and Move Reminder NPCs. The old man to the left can make a Pokemon deliberately forget one of its moves (even HM moves!) while the old lady to the right can make them remember it in exchange for a Heart Scale. Heart Scales are rare but there's one popular method involving using a Pokemon with Frisk ability and Thief move from Luvdiscs.

Luvdiscs can be fished from the sea between Ambrette Town and Cyllage City. Frisk will let you know if the Luvdisc you encountered is holding a Heart Scale while Thief will allow you to steal it. (Provided that the Pokemon using isn't holding an item) Take note that only the moves that are available for the Pokemon's type and prior to its current level can be remembered. If you taught a TM and you have made a Pokemon forget it, you have to teach the TM again since the Move Reminder can't restore it.

Leave the house then continue south to reach a barren field. Pick up the Big Root there and a hidden Nugget. Backtrack then head to the north. Go past the stairs and enter the house in the northeast corner. Talk to the old man and he'll take a look at your Pokedex for the Mountain Kalos region. If you have at least 70 different types, he'll give you a Shell Bell.

From there, head west and search the open lot beside the next house to find an X Speed. Now head south and enter the house. Talk to the girl and she'll ask if you have a certain TM. Answer Yes (if you have it) and she'll give you a Leppa Berry. Talk to the kid in the same house to get TM42 Facade. Leave the house and use the railing to the right to grind your way back to the town entrance.

Head to the south from the entrance to reach the Pokemon Center. The woman near the center sells Moomoo Milk for $500 a piece. You can buy one or a dozen. There's also a hidden Heal Ball to the southwest of the Pokemon Center entrance.

Enter the Pokemon center and talk to the woman to the right to get a Sitrus Berry. The Pokemart isn't selling anything new so just ignore it for now unless you have to restock on some items. To the left you'll find Mr. Bonding who will give you Accuracy Power.

Leave the Pokemon Center. The town's southeast exit leads to Route 17 but you won't be able to explore it without the help of a Mamoswine. Leave that for now and exit back to Route 15.
