These cartoony depictions of octopi and squid are very common in Japanese culture and other parts of Asia, with a distinct Q*Bert-like design featuring a tube-like mouth/snout on their faces, inspired by the siphons located on the backs of these animals. While the aforementioned organ serves to allow locomotion for cephalopods by expelling water in real life, in this case the siphon is subjected to some artistic liberty and made into a stylized mouth, which mainly serves to anthropomorphize them. Given how this gives the funnel-mouthed cephalopod a turret-like appearance, you can also expect its "mouth" to shoot or spit out all sorts of projectiles besides ink.
Particularly, most examples of octopi given this treatment are often colored bright red to resemble a cooked octopus, and as such are commonly used as cheerful mascots for takoyaki stands and the like.
This type of portrayal, despite what you'd initially believe, is actually Older Than They Think. The earliest example is likely The Dream of the Fisherman's Wife, an ukiyo-e piece published in 1814 depicting an octopus with its back depicted as its "face", making this trope Older Than Radio.note Octopoid Aliens in Japan tend to sport this look as well.

- Played With by a giant, man-eating octopus that Goku briefly encounters in Dragon Ball.

- Pictured above are Takosuke and Belial, two of the playable characters from Parodius.
- In the Mega Man X series, Launch Octopus is redesigned to resemble this trope, possessing a funnel-shaped vent shaft below his eyes.
- Octillery from Pokémon resembles this. Octillery even takes shooting things out of its mouth a step further by being designed after a tank, and as such it learns a wide variety of shooting or beam-type moves by level, such as Bubble Beam, Aurora Beam, Psybeam, Bullet Seed, and Gunk Shot. Its Signature Move is called Octazooka, where it damages the opponent by firing ink from its mouth, which also lowers the opponent's accuracy.

- Super Mario Odyssey averts this with the octopus-like Gushens in Seaside Kingdom, which resemble real octopi and propel themselves in the air by shooting water from their bottom. Played straight with King Mook Mollusque-Lanceur, however.
- Super Mario Sunshine: Throughout the series, the recurring black-and-white, squid-like Bloopers avert this too, but the ones from Sunshine do play it straight:
- Recurring Boss Gooper Blooper has a funnel-shaped mouth that's stuffed with a cork, which Mario must pull on in order to get it to snap back and hit him in the face. Once the cork comes off, he spits ink-like goop around the battlefield to keep Mario at bay, which Mario must wash away with water-pump F.L.U.D.D. if he wants to get close.
- The smaller Bloopers also share their boss' funnel-shaped mouths and spraying capabilities, shooting graffiti from their mouths at Mario whenever he passes by and spreading pollution everywhere.
- The aquatic, colorful variety of Bloopers you see in Ricco Harbor's surfing missions also have funnel-shaped mouths, but this time pointing downward so when viewed from above, they resemble more like actual siphons.
- Zigzagged in Super Princess Peach, where King Mook Gooper Blooper reappears as a boss and must be defeated similar to Super Mario Sunshine, where his tentacles must be Goomba Stomped in order to attack his funnel-shaped mouth. However, the trope is Averted with the game's smaller bloopers, which lack visible mouths.

- Played Straight with Sheila, a grey squid background character from SpongeBob SquarePants who stands out with her funnel-shaped mouth and realistic design compared to other cephalopods on the show. Initially, fans have passed this off as a species-exclusive trait, since prior to Season 11, she was the only actual squid character in the show compared to octopods like Squidward, whom are drawn with normal mouths or, in the case of Dr. Charley Horse from "My Leg!", beaks. Averted with One-Shot Character Squidina in Season 11's "Goons on the Moon", a squid who has a normal mouth like the rest of the main cast.
- While they aren't mouths, the long noses that octopus characters such as Squidward are drawn with also call this trope to mind.
