Super Mario 3D World
They are also an enemy appearing in Super Mario 3D World. It is a species of Blaarg, and is notably the only enemy in this group to instantly kill Mario. They appear in the final regular level in World Castle.
These enemies make yet another appearance in this game, and act slightly different. In a level, the will first drop in the lava, and then follow Mario by leaping out of the lava at him. While one or two may be easier to dodge, in large groups they can cause a lot of trouble.
