A Goomba is a small, brown, sentient mushroom, used as an enemy in Mari0 . It is the lowest of Bowser's lackeys.
For more information on Goombas within the Mario universe, please refer to the Super Mario Wiki.
In-Game[]
A Goomba will walk to the left at a constant speed until it hits something and changes direction. Goombas will stack on top of other enemies, and can be flung by Faith Plates, can walk on or be blocked by Hard Light Bridges, carried by Excursion Funnels, killed by Lasers and will walk on platforms of all kinds. To attack Mario, a Goomba must touch him from the side, whereupon Mario will either shrink or lose a life.

"Also boxes kill Goombas because why not."
Goombas can be killed in many ways. The most frequent is by Mario jumping on them, which will cause them to squish and disappear. Fireballs are an important method of dispatch as well. Goombas can be redirected via portals into a pit; sometimes they'll just walk off on their own. Lasers will kill them automatically, as will Emancipation Grills; cubes dropped on them will have the same effect as Mario jumping on them. If a Goomba is standing on a Brick Block, and Mario hits it from below, the Goomba will fly off the screen. A Koopa Shell will also KO a Goomba, and the points accrued from killing multiple may grant Mario an extra life.
How to Use[]
To place a Goomba, choose it from the editor and place it in the position it will appear in. There are two ways to position a Goomba—the normal way (where it takes up the whole block), and shifted half a block to the right.
Strategies[]
- A Goomba will not begin moving until the camera is within a block of its starting postition. This information is useful for timing a Goomba's position so that Mario reacts in a predictable manner (often toward his doom).
- Since Goombas can stack and be placed at half-block intervals, it is possible to create a Goomba pyramid (although the way they appear onscreen may hinder this).
- It is possible to use a Goomba and several buttons to create a shifting obstacle out of Portal elements such as doors or lasers, which is useful when Square Waves cannot be used, such as in 1.6.
- Goombas are deadly surprise attackers when used with Faith Plates.
- You can stack a Goomba on top of another enemy, like a Koopa, to shield that enemy.
- As they depress Buttons, like Cubes, Goombas can also be used for puzzles in otherwise Portal-style mappacks, taking advantage of their constant motion. This is made easier in SE, where than be dispensed from Droppers.
Will Smith[]

A Goomba is seen hiding behind a portal on the Mari0 title screen, officially christened Will Smith by Sašo. The Mari0: SE title screen shows the other side of the portal, with Will Smith's full body. This sprite has a slight design difference from the standard Goomba, as the feet are colored grey rather than black (though this is likely just due to the black background).
Naming[]
On the Stabyourself.net Forums, Turret Opera made a thread called Title Goomba Appreciation Thread, all about this Goomba. Amidst a debate about what the Goomba's name should be, Sašo suddenly posted "It's Will Smith." and it was settled. (The thread was promptly renamed to Will Smith Appreciation Thread.)
Balloon Goomba[]
Balloon Goomba is an enemy that appeared in a single level in New Super Mario Bros U and isn't the most appealing enemy, However was constantly suggested for the mod Alesan's Entities by a user. It has now become one of the most popular Mari0 "memes" being constantly used as a joke for suggesting stupid features. Many custom enemies and even a sever was made in honour of this enemy that nobody wanted.
Trivia[]
- In the original Super Mario Bros., Goombas only have a single walking sprite, which is flipped back and forth to give the effect of shifting feet. They were added very late into development to serve as an easier enemy than the Koopas, so this was done to save space on the cartridge. This animation quirk holds true in Mari0, rather than having the flipped sprite as a separate frame.
- In Super Mario Bros., the Goomba palette is replaced by the Blooper palette in the water levels, so an underwater Goomba would have appeared with the same colors as a Blooper. However, no underwater levels actually contain Goombas (except in The Lost Levels), so this is not replicated in Mari0; instead, the underwater spriteset for Goombas is identical to the overworld spriteset.
