Nipper Plant

Nipper Plants, also known as White Piranhas , Walking Piranhas or Walking Piranas , are infant Piranha Plants. They are rather small and are usually white.

Super Mario Bros. 3
They first appeared in Super Mario Bros. 3, where they would patrol an area and jump up towards Mario or Luigi when he passes them. Nipper Plants can hop around, making it more difficult for the player to land safely, since the plants will harm Mario or Luigi if he attempts to stomp one. Instead, Nipper Plants can be defeated by Invincible Mario, Fire Mario's fireballs, Hammer Mario's hammers, Raccoon Mario's tail attack and Tanooki Mario's transformation. In subsequent remakes, they were re-colored pink rather than the usual white. In all versions, a jumping Nipper Plant is a recolor of two Muncher frames.

A sessile fire breathing variety is encountered at the end of World 7-8. There is only one of these Fiery Walking Piranhas in the entire game.

The Adventures of Super Mario Bros. 3
Nipper Plants make a few appearances in The Adventures of Super Mario Bros. 3. In these appearances, they behave much like their game counterparts in that they are capable of hopping around. On the show, Nipper Plants sport visible jaws that make them appear to be more menacing than their in-game counterparts.

Nintendo Adventure Books
Wendy O. Koopa is revealed to have a pet Nipper Plant, which she keeps in a pot in her room, in Koopa Capers; the plant had shredded a note possibly pertaining to her whereabouts. If Luigi chooses to begin his search for the missing Koopaling by looking through her room, he accidentally wakes up the sleeping Nipper Plant when he tries to look under it. Some wild Nipper Plants later appear prowling the stairs leading up to the secret camp being used by Wendy and her rebellion.

Yoshi franchise
In Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3, Nipper Plants do not jump at Yoshi and are much easier to defeat, but they appear in groups which adds to the challenge of defeating them. They hatch from Nipper Spores that slowly fall to earth and have no visible eyes. These Nipper Plants can be stomped or eaten and turned into eggs; their spores can also be swallowed, though no eggs will be produced as a result.

Nipper Plants and their spores reappear in Yoshi's Story, Yoshi's Island DS and Yoshi's New Island.

Nipper Plants reappear in Yoshi's Woolly World, acting the same as in previous games.

Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, Nipper Plants (under the name Chompweed ) could not be battled. Rather than fighting Mario, they would jump up and steal a few Coins if the plumber got too close. Stolen coins could not be recovered in the final game, but battle data for them still exists, suggesting that they may have been intended to be standard enemies at one point.

Super Princess Peach
Nipper Plants also made an appearance in Super Princess Peach, which were identical to the ones that appeared in Super Mario World 2: Yoshi's Island. A Gloom vibe-infused variety known as Sad Nipper Plants also appeared in this game.

Mario Kart Arcade GP
Some Nipper Plants made a cameo appearance in Mario Kart Arcade GP in the course Bananan Ruins. They are at the right side of the course. They also appear in the course Castle Wall.
