Super Mario World
The Volcano Lotus appeared in many levels spitting a few fireballs into the air at a diagonal angle. In order to defeat them, Mario must twirl his cape or Yoshi must eat them. Spin jumping or stomping on it while riding on a Yoshi never harms them but makes Mario bounces off and Mario doesn't take damage.
Super Mario World (TV series)
Super Princess Peach
A Volcano Lotus made its latest appearance in Super Princess Peach. Princess Peach fights them instead of Mario or Luigi. A Swatbrella attack or any other attack can kill it. They are called "Volcano Plants" and a subspecies of it is a Calm Volcano Plant, where it sees Princess Peach and spits fireballs at her.
