Volcano Lotuses are a type of plant that shoots fireballs vertically as attacks. It first appears in Super Mario World.
Super Mario World
They appear in many levels, spewing small fireballs into the air at a diagonal angle, which proceed to slowly rain down on the surrounding area after reaching their highest point. To defeat them, they must be hit by whirling Mario's cape next to them or eaten, stepping on them while riding Yoshi.
Super Princess Peach
They were also known as "Volcano Plants". It throws fireballs which Peach should avoid and they created their first appearance in Ladida Plains. They even have their own sub-species, Calm Volcano Plant.
