River Piranha Plant

River Piranha Plants are variants of Piranha Plants that appear in New Super Mario Bros. Wii, New Super Mario Bros. U, New Super Luigi U, Super Mario Run in the update (3.0.4) and New Super Mario Bros. U Deluxe, and greatly resemble the Jumping Piranha Plant of Super Mario World in design. They appear in World 5-1 as common enemies in New Super Mario Bros. Wii. They also appear in Fliprus Lake and Seesaw Bridge in New Super Mario Bros. U. As their name implies, they live in rivers. When Mario is not around, they blow green spike balls like a Ptooie's method of attacking. When Mario approaches, however, they suck in and bring the spike ball to their lips and slowly blow it upwards to attack. Just like regular Piranha Plants, they can be defeated with fireballs or a Super Star. The spike ball itself can be taken out with a shell or the Super Star, after which the River Piranha Plant will sweat and panic in place, unable to do anything.

In New Super Luigi U, River Piranha Plants appear in quicksand as well as water. Their behavior does not change.

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