Big Piranha Plant

A Big Piranha Plant (also known as Piranhacus Giganticus, Super Piranha Plant or Mega Piranha Plant ) is a gigantic variety of Piranha Plant.

Super Mario Bros. 3
In Super Mario Bros. 3, they only appear in Giant Land. Although they are huge, a single fireball will destroy them, and they are mostly the same as any other typical Piranha Plant, other than presenting a larger target and obstacle; however, they will pop out even if Mario is next to their pipes, like the red normal-sized Piranha Plants in Super Mario Bros.: The Lost Levels. They also appear in larger pipes than other Piranha Plants. In the NES version, most of them have red heads and red leaves, except for the ones in World 4-6, which have green heads and green leaves. In the remakes, all of them have red heads and green leaves.

New Super Mario Bros.
Super Piranha Plants are found in the game New Super Mario Bros. Unlike their previous appearance, Super Piranha Plants are never seen in pipes due to their size. Fire Mario must shoot three fireballs at one to destroy them. When defeated, they give up eight coins instead of the usual one coin.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Super Piranha Plants function the same as before. Upon defeat, they now give up three coins instead of eight. Its fiery counterpart also makes its debut in a sidescroller.

Super Mario Galaxy 2
Super Piranha Plants appear alongside Giant Goombas, Big Paragoombas, and Giant Koopas in Super Mario Galaxy 2, where they appear in the Supermassive Galaxy. They are shown in giant pipes similar to how they appear in Super Mario Bros. 3, only much bigger. However, in contrast to their original appearance in Super Mario Bros. 3, they are invincible, thus serving more as an obstacle than an enemy. They can, however, be stunned with a spin or a Star Bit, but that just hinders the player as it stops the plant from going back in the pipe.

New Super Mario Bros. 2
In New Super Mario Bros. 2, Big Piranha Plants are among the enemies that are affected by the Gold Ring. When defeated, the location they once stood upon spouts coins. They once again exclusively appear outside pipes, just like in New Super Mario Bros. and New Super Mario Bros. Wii.

New Super Mario Bros. U
In New Super Mario Bros. U, Big Piranha Plants are seen in numerous stages, such as Rise of the Piranha Plants. One Big Piranha Plant is also featured in the Boost Rush level Piranha Plant Hideaway. A shortcut for this level is to have the player utilizing the Wii U GamePad rapidly tap on the Big Piranha Plant, creating room for the player to jump over its head, reaching the goal ring. Notably, Jungle of the Giants is the only level to feature the classic pipe-dwelling Big Piranha Plants, making this the first game to show them alongside the newer grounded variant.

New Super Luigi U
Both forms of the Big Piranha Plant reappear in New Super Luigi U. Piranhas in the Dark introduces upside-down versions in dirt, and Giant Swing-Along introduces upside-down versions in pipes.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
Mega Piranha Plants appear in Super Mario 3D World and Super Mario 3D World + Bowser's Fury. Like normal-sized Piranha Plants in modern 3D games, these can be stomped to be defeated, but two stomps are required to do so, with the first stomp merely stunning them. This is their second appearance in a 3D Mario game.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Big Piranha Plants reappear in Super Mario Maker and Super Mario Maker for Nintendo 3DS. The player can enlarge a normal Piranha Plant with a Super Mushroom, and it will transform into its larger variant. They return in Super Mario Maker 2, where they attack by lunging at the player in the Super Mario 3D World style.

Super Mario Odyssey
While regular Big Piranha Plants do not appear in Super Mario Odyssey, Big Poison Piranha Plants appear, where they can be found in the Wooded Kingdom, the Metro Kingdom, and the Dark Side.

Super Mario World 2: Yoshi's Island
In Super Mario World 2: Yoshi's Island, a regular Piranha Plant named Naval is transformed by Kamek into a giant-sized Piranha as a boss of World 3.

Mario Golf: World Tour
Big Piranha Plants reappear as obstacles in Mario Golf: World Tour. This is the first appearance of Big Piranha Plants in a Mario Golf game.

Captain Toad: Treasure Tracker
Exclusively in the Wii U version of Captain Toad: Treasure Tracker, one Big Piranha Plant reappears in the bonus level, Shadow-Play Alley. These enemies do not return in the Nintendo Switch and Nintendo 3DS versions since the level is not included in them.

Mario Kart Arcade GP VR
Big Piranha Plants reappear in Mario Kart Arcade GP VR, where they appear in the start of the track, where they bite down on patches of dirt making any racer who touches them spin out.

Mario Kart Tour
In Mario Kart Tour, Big Piranha Plants in large pipes reappear as stage hazards in the wide, muddy area of Choco Island 2T, and in the middle of the roundabout opposite the in Paris Promenade 1.

Mario Party: The Top 100
A Big Piranha Plant appears in the Mario Party: The Top 100 version of Tug o' War where it eats the loser(s) that gets tugged into its jaws.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, Big Piranha Plants (just called Big Piranhas) are mentioned briefly by Viridi during Palutena's Guidance dialogue for Piranha Plant. Unlike most other variations generally mentioned in order of appearance, they are listed amongst New Super Mario Bros. Wii debuts. Nipper Spores, Big Fire Piranhas, Small Piranhas, and Fire Stalking Piranhas are similarly listed out of order.

Trivia

 * The "Piranhacus Giganticus" name is given in binomial nomenclature, a scientific way of naming species, with the words "piranha" and "gigantic" altered to fit the Latin grammatical form, itself a practice known as.
