Potted Piranha Plant

Potted Piranha Plants are, as the name implies, Piranha Plants inside pots.

Mario Party 3
Potted Piranha Plants made their first appearance in the Mario Party 3 minigame Storm Chasers, where the players needed to water their Piranha Plants by chasing a rain cloud. The player who gathers the most amount of water for their Piranha Plant wins.

Super Mario 3D World
Potted Piranha Plant is an item 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.

Mario Kart 8
The Potted Piranha Plant also appears in Mario Kart 8 as an item, now simply called Piranha Plant. The Potted 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 do a manual chomp by pressing. However, the downfall is it can only chomp what is in front of it, leaving the player vulnerable to some items.
