Potted Piranha Plant

Potted Piranha Plants are items that are a type of Piranha Plant that only reside in pots and can be picked up and carried.

Mario Kart Arcade GP subseries
In both Mario Kart Arcade GP and Mario Kart Arcade GP 2, the Piranha Plant is one of Princess Peach's special character items. The Potted Piranha Plant's function in both games is that of eating the items of Peach's opponents once it is summoned by her. In Mario Kart Arcade GP, it is differentiated from normal Piranha Plants by its bright pink coloration (possibly in reference to Peach herself). It returns in Mario Kart Arcade GP DX.

Mario Kart 8 / Mario Kart 8 Deluxe
The Potted Piranha Plant also appears in Mario Kart 8 and its enhanced port, Mario Kart 8 Deluxe, as an item. The Piranha Plant is set up in front of the user, biting any opponents, items such as Bananas, Bloopers, shells, and objects such as coins and traffic cones that they pass until it disappears. It also gives the user a speed boost every time it lunges out to chomp, which it automatically does every few seconds. The player can also manually have it chomp by pressing the item button. However, the plant can only chomp items that are in front of it, meaning that the player can be hit from other directions. In this game, the pot has wheels on the side. These wheels turn sideways when going into anti-gravity. The Piranha Plant will spin around as the result of a trick.

In Mario Kart 8 Deluxe, the Potted Piranha Plant is used in the game's exclusive battle mode, Renegade Roundup, for the Authorities to capture Renegades on the other team. In that mode, the Piranha Plants have a strobe light on top of their head. When an opponent is nearby its strobe light will turn on and its siren will blare. The color of the Piranha Plant and its strobe light varies depending on which team it is on. If a player with a Potted Piranha Plant is hit with an item in this mode, stars will appear over the Piranha Plant's head to indicate that it is stunned and unable to capture an opponent. If the player drives into the wall or rim, the Piranha Plant along with pot it is in will disappear until the player drives away from the wall or rim. In the North American overview trailer, the item is misspelled Pirahna Plant.

Super Mario 3D World
The Potted Piranha Plant is an object that can be used by any playable character in Super Mario 3D World. The Piranha Plant eats most enemies and is able to grab Green Stars out of reach of the playable characters. They first appear in Shadow-Play Alley, and last appear in Champion's Road. Players can also defeat them by jumping on them or throwing an item at them. Potted Piranha Plants also attack other characters; however, the characters get stunned and knocked aside rather than powered down. Shadow-Play Alley's Stamp is a potted Piranha Plant.

Captain Toad: Treasure Tracker
Exclusively in the Wii U version, Potted Piranha Plants return in Captain Toad: Treasure Tracker. Here, they are used by Captain Toad exactly like in Super Mario 3D World, although they only make appearances in Shadow-Play Alley and other returning levels.

 * Instruction manual bio: "Attaches temporarily to the front of the vehicle. When the Piranha Plant bites at something, the momentum of its lunge provides a slight speed boost."
