Inky Piranha Plant

Inky Piranha Plants are enemies first appearing in Super Mario 3D Land. They resemble normal Piranha Plants, but they are black instead of red and can spit ink to cover the player's screen, similar to a Blooper in the Mario Kart series.

Super Mario 3D Land
Inky Piranha Plants appear mainly in the underground levels. They spit ink out of their mouths to cover the screen. If the player blows into the microphone, though, the ink will be blown off, removing it from the screen. They can be defeated by any attack method, just like a normal Piranha Plant.

Mario Tennis Open
Inky Piranha Plants appear in Mario Tennis Open. In Ink Showdown, a revamped version of the Piranha Challenge from Mario Tennis, they shoot tennis balls to the player, as well as ink blobs that will block their screen making it harder to see.

Mario & Luigi: Dream Team
Inky Piranha Plants appear as background enemies in Mario & Luigi: Dream Team. Inky Piranha Plants do not appear in the field due to their nature of a background enemy, and only randomly appear during battles against Fire Bros and/or Flaming Antasmatons in the later segments of Neo Bowser Castle.

In battle, Inky Piranha Plants will spit ink at the screen, just as in Super Mario 3D Land, making it difficult to see and avoid enemy attacks. Unlike most background enemies, it cannot be brought into the foreground whatsoever, and the use of a single Taunt Ball will simply knock it unconscious, rendering it unable to shoot ink for several turns. Once again, unlike most other background enemies who are defeated through use of a Taunt Ball, Inky Piranha Plants can be defeated if a total of three Taunt Balls are thrown at one by either Bro.

After an Inky Piranha Plant spits ink on the screen, it can be cleared off quickly by blowing into the 3DS microphone.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, Inky Piranha Plants (just called Inky Piranhas) are mentioned briefly by Viridi during Palutena's Guidance dialogue for Piranha Plant.

Mario Kart Tour
Inky Piranha Plants make their Mario Kart series debut in Mario Kart Tour as obstacles on the Bangkok Rush course.

Paper Mario: Sticker Star
Inky Piranha Plants were going to appear in Paper Mario: Sticker Star, but were cut from the game.
