Hotlantis



Hotlantis is a general store run by Harmony in Splatoon 3. It is located in Splatsville, and can be accessed from Inkopolis Plaza through the arcade machine after downloading the.

Description
Hotlantis sells stickers, posters, and other cosmetic items for decorating in the locker room that can be purchased with cash earned from multiplayer matches, Salmon Run shifts, and "simple" Mystery Boxes. The store's in-game catalog features seasonal items that are collected as the player's catalog level goes up. The catalog is also swapped out for a fresh one with new items every three months.

Players can click to show the scale of the selected item compared to their locker, and pressing  purchases this item. Pressing allows players to enter Crush Station and pressing  similarly allows them to enter Ammo Knights, while pressing  takes players back to the square in Splatsville. If the player is in Inkopolis Plaza, pressing takes them to Shrimp Kicks, rather than Crush Station. Pressing takes players back to the plaza.

The manager of Hotlantis is rarely present, so the shop is instead run by Harmony, one of its frequent customers.

While Hotlantis does not exist in Inkopolis Plaza, the arcade machine formerly found there has been converted into a terminal that the player can use to access the store remotely. The player does not appear in the store; instead, Harmony looks down at her Sea-Cucumber Phone, presumably using it to communicate with them. A new remix of Lookin' Fresh plays when accessing Hotlantis from the terminal.

Quotes
"Fortunately, cool stickers and other decorations can be obtained locally at Hotlantis. Nobody knows the store better than Harmony, who has spent so much time shopping there that the owner pretty much leaves her in charge. Check in daily for a rotating selection of goodies!

Oh, you can also get your catalog at Hotlantis! The catalog is filled with seasonal gear and items that you can collect by participating in battles and taking on Salmon Run jobs. There's a new one every three months, so you'll always have a fresh selection to keep you busy."

"Visit Hotlantis in #Splatoon3 to grab items to snazz up your locker, as well as a seasonal catalog offering various goodies such as Splashtags and seasonal gear. Not sure where the owner is, but former regular Harmony tends to the store on their behalf."
