Mini Goomba

Micro-Goombas, also known as Mini Goombas, are miniature Goombas that were featured throughout different installments of the Mario series. They look like regular Goombas, being brown vaguely humanoid mushrooms, albeit they are notably smaller in size. Their main purpose is usually to slow down the players or otherwise impede their progress. They first appeared in Super Mario Bros. 3.

Super Mario Bros. 3
In Super Mario Bros. 3, Paragoombas would drop Micro-Goombas onto Mario and Luigi, which highly weakened their ability to Jump temporarily. They were also known as Mugger Micro-Goombas.

They first appear in level 1-2. When the Micro-Goomba is launched, it will slowly float to the bottom of the screen. If they collide with Mario or Luigi, they will cling onto him which slows them down and prevents them from jumping high. Mario or Luigi will have to jump repeatedly to knock the pesky creatures off of them. Pile Driver Micro-Goombas also appear.

Super Mario 64
They also appear in Super Mario 64 ' s Tiny-Huge Island. They appear in the tiny side, and if they touch Mario, he will not get hurt, only knocked a few feet back, and the Micro-Goombas will die. However, they are usually placed near bottomless pits or cliffs, and will often knock Mario off into these. They can easily be defeated by jumping on their heads, or by punching or kicking them. They are slightly faster than regular Goombas and they give off a Coin when defeated, which apparently is twice as large as the Micro Goomba itself. Micro-Goombas also appear in the remake, Super Mario 64 DS.

New Super Mario Bros.
They reappear in New Super Mario Bros.. When Mario is Mini Mario, he can enter miniature pipes. If he enters one, Mario may find a Star Coin. However, in some cases, Micro-Goombas are in the way, and Mario has to defeat them to get to the Star Coin. In this game, Micro-Goombas possess the intelligence of any other Goomba. As Mini Mario, they can be defeated by jumping on them, but by any other form of Mario, they can be defeated by even simply walking into them. They are the only enemy in the game which Mini Mario does not need to Ground Pound to hurt or defeat.

Super Mario Galaxy
Micro-Goombas reappear once again in Super Mario Galaxy, this time being slightly larger than the regular-sized Micro-Goombas and looking more like Galoombas from Super Mario World in terms of shape. They are rare enemies, as they are only found in two levels: The "Grand Star Rescue" mission of the Gateway Galaxy, and later in Bowser Jr.'s Lava Reactor during "King Kaliente's Spicy Return". They act in a different manner than Goombas in this game, as spinning and instantly defeating them only yields a coin instead of three Star Bits. Micro-Goombas also appear in Super Mario Galaxy 2, where they are more common, and leave Star Bits behind when defeated with a spin instead of a single coin. They Resemble Galoomba's in this game

New Super Mario Bros. Wii
They reappear in New Super Mario Bros. Wii, this time in the open world. Mostly in groups, they are not dropped by Paragoombas, but they still weigh Mario down by swarming on him. They cannot hurt Mario if he is not in his Mini form. However, the plumber can do a Spin Jump to get the pesky enemies off. After being spun once, Micro-Goombas are defeated. Despite their size, Micro Goombas still let out a coin when hit by a fireball. They made appearances on World 5-4 and 7-5.

New Super Mario Bros. 2
Micro-Goombas reappear in New Super Mario Bros. 2. They act the same as they did in New Super Mario Bros. Wii. They can be defeated by simply jumping on their heads, like regular Goombas. If they attach themselves to the player, the player can ground pound to get rid of them, attack them as Raccoon Mario, or simply walk around for a few seconds until they go away. They are no longer dropped by Paragoombas like in Super Mario Bros. 3, and instead are seen simply walking around. They also appear in gold form in World 5-3 and World 4-1. They can only be seen in 5-3 by getting a Gold Ring, going fast to the Cannon Pipe or using the Super Leaf to fly up to the Micro Goomba's platform when Mario or Luigi get to the edge of the first cliff after getting the second one.

New Super Mario Bros. U
Micro-Goombas return once again in New Super Mario Bros. U acting as the prequels. They mainly appear in a level Magma-River Cruise of Peach Castle although a large number of them appear.

Super Mario 3D World
Micro-Goombas are set to reappear in Super Mario 3D World, keeping their appearance from New Super Mario Bros. games. However, this time they can actually hurt the player upon contact. They attack in groups, and can also be released from Crates. Additionally, ground pounding near a Micro-Goomba causes it to be knocked away.

Nintendo Adventure Books
While Mario is exploring the Mushroom Kingdom in Double Trouble, he can encounter a swarm of Paragoombas, which begin dropping Micro-Goombas on him. If Mario decides to pick the Micro-Goombas off instead of running for cover, the tiny Goombas will knock him out with some noxious gas, though their parents will leave him alone after finding him unappetizing. If Mario makes a run for some pipes instead, he will pick the Micro-Goombas off, and be left alone when the Paragoombas grow bored of waiting for him to come out.

Super Mario RPG: Legend of the Seven Stars
A similar species called Goombettes are found in Super Mario RPG: Legend of the Seven Stars. They reside in the Sunken Ship as enemies, and a group of them (The Triplets) ran a shop which was originally run by a normal Goomba. The Shop sold Mushrooms that heal 30 HP, but turn the player into a mushroom, possibly referring to the slowing down effect of the Mugger Micro-Goombas. However, the party member who ate the mushroom steadily heals his HP as long as the Mushroom Status remains.

Super Princess Peach
In Super Princess Peach, Mugger Micro-Goombas from Super Mario Bros. 3 reappear helping Bowser in his conquest of Vibe Island, this time however, they completely weigh down the player. They have to use the Rage vibe or the Joy vibe to get them off.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, in the Mrs. Thwomp battle, Micro-Goombas make up the miniature clones.

Super Paper Mario
In Super Paper Mario, Micro-Goombas are not seen but only mentioned. A resident in The Underwhere mentions that he died all because of a Micro-Goomba and a bottomless pit. A Sammer Guy named "Micro Boomba" is a reference to this type of Goomba.
