Superball Mario is the most powerful form Mario can achieve in Super Mario Land, obtained by collecting a Superball Flower while in Super Mario form. If Small Mario collects a Superball Flower, he will first transform into Super Mario, then immediately into Superball Mario. This form grants Mario an offensive projectile, making him much more capable of dealing with enemies from a distance.

Characteristics:
- Size: Same as Super Mario (taller).
- Abilities: Can shoot Superballs by pressing the B button. Superballs bounce off surfaces at a 45-degree angle and can defeat most enemies. They can also collect coins through blocks.
- Defense: Same as Super Mario; can take one hit of damage, reverting to Small Mario.
Strategy when Superball Mario:
- Utilize Superballs constantly: Don't be shy about using your Superballs. They are unlimited and incredibly effective against most enemies, especially flying ones or those in hard-to-reach spots.
- Clear paths: Use Superballs to clear enemies ahead of you, making platforming safer.
- Collect hidden coins: Aim Superballs at suspicious block formations or areas where coins might be hidden behind walls. The Superball can pass through blocks to collect them.
- Boss battles: Superballs are essential for defeating most bosses in the game.
- Maintain the power-up: Just like Super Mario, avoid taking damage to stay in this powerful form.
Superball Mario is your ultimate weapon against Tatanga's forces. Mastering the bouncing trajectory of the Superball is key to maximizing its effectiveness. Always try to maintain this power-up, as it significantly eases the difficulty of many stages and boss encounters.
