|~ Their catchphrase|
The Squid Sisters are two Inklings named Callie and Marie from the video game Splatoon. They are the hosts of Inkopolis' news. In the single-player mode, respectively, they're also both known as Agents 1 and 2 of the New Squidbeak Splatoon.
Callie has black/pink hair, a pink and white hat resembling the Japanese food, ikayaki, a sleeveless outfit that ends in shorts, pink tights and hair that resembles a female Inkling's, but behind. Marie has white/green hair, a green and white hat resembling a calamari ring, a sleeveless outfit that ends in a skirt, green tights, black shorts, and short hair, unlike Callie.
In Splatoon 2, while under DJ Octavio's influence, Callie wore an entirely different outfit than her Squid Sisters outfit. She wears a small black crop top, which easily exposes her midriff area with three pink marks that are fairly similar to the three marks on her Squid Sisters outfit, and also reveals a pink octopus-like tattoo around the navel area. She still wears earrings, but they now appear to be golden octopus-shaped earrings. She now wears shorts that are made of black leather, also wearing dark-magenta leggings, which sport a galactic texture. Her most iconic features are her hypnoshades, which were used to, as the name implies, hypnotize her into working for DJ Octavio. When she returns to normal and appears back in Octo Canyon, after Octavio is defeated for the first time, though Callie won't appear in Octo Canyon until after a bit, she wears a casual getup: donning a white shirt as well as a black undershirt, while also wearing a pink hoodie, and she also wears black shorts and a pair of brown heeled shoes with pink socks. She also once again appears wearing the earrings that she wore in Splatoon and also wearing a pink beanie with a star on it, the same star and pink beanie she wears when posing as Agent 1 in the first game.
In Splatoon 2, Marie wears a dark-grey kimono with a very distinct design pattern on the robe, as well as holding a parasol with the Cuttlegear logo on the canopy and also wears traditional Japanese sandals. Also, both Callie and Marie wear gloves, white collar necklaces, and white, chunky earrings.
In Splatoon, they usually host the news, as well as the Splatfests that they used to be the performers for. When Cap'n Cuttlefish was captured in after Agent 3 defeated the third boss, they were called in by him to be the latter's guide and to help them find and retrieve the Great Zapfish. They will then reveal themselves to Agent 3 as the Squid Sisters, after overriding Octavio's music with their own, singing the song "Calamari Inkantation".
In the sequel, Marie can be seen standing over a manhole cover in Inkopolis Square, which leads to Octo Canyon, the single-player campaign mode. When entering the manhole, Marie appears standing across from the now-Agent 4 of the New Squidbeak Splatoon, with her back facing toward the player, she then introduces herself as Marie of the Squid Sisters, however, much to her shock, Agent 4 doesn't know anything about them. She also indicates to Agent 4 that, in truth, she is Agent 2. After Agent 4 makes their way through Octo Canyon, defeating the Octarians and their new war machines to retrieve the Zapfish in each area, Agent 4 reaches the stadium where many Octarians have gathered, only to find Callie there, now under the freed DJ Octavio's control as he uses the Great Zapfish to power his new DJ stage, the Octobot King II. Marie soon arrives with Sheldon to free Callie from the effects of the hypnoshades Octavio placed on her, and once reminding Callie of "Calamari Inkantation", Marie is able to fully snap Callie back to her senses, as Callie leaps from the Octobot King II to Sheldon's truck, changing back into her stage outfit from what Octavio put her in, and together, the Squid Sisters perform "Spicy Calamari Inkantation" to once more override Octavio's music while Agent 4 is supplied a modified Rainmaker from Sheldon to finish off Octavio and the Octobot King II. With Octavio defeated and the Great Zapfish recovered again, the Squid Sisters resume their music career, even with the new opposition with Off the Hook having taken over the Inkopolis News duty from them in Inkopolis Square.
- It was revealed that they're Cap'n Cuttlefish's granddaughters.
- Despite their title being the "Squid Sisters", they're actually cousins.
- If the player talks to Marie long enough, she'll start thinking of insulting and bizarre things, such as thoughts that are off-topic, like her wanting "pineapple-free pizza from the future".
- However, Marie does think of one nice thing about Agent 4, thinking that they're "pretty adorable", possibly having a crush on them.
- The same thing happens if the player talks to both Callie and Marie long enough, but Callie thinks far nicer thoughts about Agent 4, including some off-topic things as well, like "Gotta remember to check the new script and memorize my lines when I get home..."
- The reason Callie went missing in Splatoon 2, was because Marie gained more popularity after winning the last Splatfest for Splatoon.
- In the hero mode for Splatoon, Callie nearly revealed Marie's true identity to Agent 3.
- During the final boss battle in Splatoon 2, both Callie and Marie are seen wearing their iconic Squid Sisters outfits.
- It is theorised by fans that Callie and Marie are not squid but Cuttlefish,this is yet to be confirmed by Nintendo.
