When you arrive, do the usual healing and shopping. Or so you’d expect, but Pacifidlog doesn’t have a Poké Mart. Assuming you came here after battling Primal Groudon/Kyogre in the Cave of Origin, Surf to the left of the Pokémon Centre to find some Kangaskhanite .
This stone is obviously meant to Mega Evolves Kangaskhan, perhaps the most-used Pokémon - and definitely the most-used Mega - of the X/Y competitive Pokémon scene. If you stand where you found it and then face south and press A, you’ll also find a Big Pearl.
In the house west of the Center, the man at the back will hand you TM56 (Fling). Fling is a move in which the user throws its item at the target, and is usually one-time, but, in that one use, it makes a nasty nuking move under a number of circumstances.
In the house to the east of the Center you can hear a bit about the Regi Pokémon lore, in particular the "Six dots open three doors" quote, which could reference any number of things about the quest: the Braille, the symbol on each Regi, the rocks around their shrines
In the southwestern house of town, if you bring along a Pokémon with high Happiness when speaking with the man there, you’ll get TM27 (Return); similarly, a Pokémon with low Happiness will yield TM21 (Frustration).
Return and Frustration are moves that rely on a Pokémon’s Happiness to deal damage; they are Normal moves, whose Base Power ranges from 1 to 102. Most Pokémon can learn these moves, and you probably have high-Happiness Pokémon right now if they’ve been in your party for a while.

In the next house to the east of there, you can trade your Bellossom for a woman’s Corsola; since it’s much harder to get Bellossom (Gloom and a Sun Stone) than Corsola (just Fish or Dive or something), it’s better just to ignore it altogether.
From there, go to the east house; you can use the Dowsing Machine just outside of its front door to find a Heart Scale . Within, the man will give you TM03 (Psyshock).
Psyshock is basically the Physical version of Psychic; whereas both use Sp. Atk., Psyshock is slightly weaker and uses Defense and Psychic uses Sp. Def. This can be very significant at times in the competitive environ, but it’s better just to stick with Psychic unless you don’t have that either.
Anyhow, we’re done here. Surf west from the town to the current-filled Route 132 .
