Bone Piranha Plant
From the Super Mario Wiki
Bone Piranha Plants are a variety of undead Piranha Plant debuting in New Super Mario Bros. 2. They are skeletal versions of normal Piranha Plants with some changes, such as a grayish cranium, holes rather than spots, greenish-gray lips, vertebrae instead of a plant stalk, and dark, gray leaves that appear dead.

Besides these graphic changes, its attack patterns appear the same than those of a regular Piranha Plant. However, unlike normal Piranha Plants, and like Dry Bones, they are immune to fireballs. They can be defeated by a Super Leaf tail spin, Star or a Gold Flower, however. They are only found in Towers and Castles. They are extremely common in World 4-.
Mario Party: Island Tour
Bone Piranha Plants also appear in Mario Party: Island Tour on the Bowser's Peculiar Peak board. If the player lands on a space that moves them forward a number of spaces, the Bone Piranha Plant appears, chews them up, and then throws them forward.

Puzzle & Dragons: Super Mario Bros. Edition
Bone Piranha Plants are present in Puzzle & Dragons: Super Mario Bros. Edition, where they own the Wood attribute, but also the Dark attribute. As such, they appear to be very weak to the Fire attribute, yet strong to the Water one. They show a lack in HP and RCV ratings, but this is completed by their dangerous amount of attack points. Poison Mist is the name of their main skill, which switches Water and Fire orbs of enemies to their own attribute orbs - Wood and Dark, respectively. Bone Piranha Plants can be fought in some levels of World 8.
