Inkopolis News Studio
The name(s) presented could be conjectural.
The Inkopolis News Studio is where the Squid Sisters film Inkopolis News. It is located in Inkopolis Plaza, next to the Battle Dojo and on top of Inkopolis Café. It cannot be entered, although Inklings on the Plaza can go up to the walkway to the Battle Dojo, and keep going to reach a balcony where they have access to the studio's window. From here, they can see the Squid Sisters. Template:S2' studio can be found next to The Shoal, with Off the Hook in it.
Easter Egg
There is an Easter egg here: if the player looks through the studio's big glass window, the Squid Sisters or Off The Hook will eventually turn to the player and wave. Pearl will shoot the player an annoyed look for disturbing her conversation and pose, Marina will bashfully wave. If the player is an Octoling, the two will happily wave, because they recognize the player as Agent 8. Both of the Squid Sisters smile and wave.
Appearance
Splatoon
In Splatoon, the Squid Sisters sit on chairs. The color of the enemy team in your latest match and your recent team color appear on the chairs. The table in front of them has two lollipops on it, inside a container.
Splatoon 2
In Splatoon 2, Off the Hook also sit on chairs (Pearl's is yellow but Marina's is black) and on the table there is what appears to be a bag of chips, and a drink.
Usage
Here, Inkopolis News is filmed. In Splatoon, people also order food and drinks, as there is a café beneath it. In Splatoon 2, there is a second floor, possibly used to film movies or music videos.
