The Mini Mushroom is a Power-Up seen in various modern Super Mario Bros. games. When collected, they make the player tiny, and usually make it so that the player cannot kill any other enemies unless they ground pound on them.
Super Mario 64 Manifestation[]
Mini Mushrooms are normally found in yellow ! boxes, but they can also be found rarely in small dark blue boxes, and normally act like 1-Ups, specifically ones that try to avoid the player.
Mini Mushrooms are mainly found in Tiny-Huge Island and Big Boo's Haunt, but there have been reports of them showing up in other levels such as Bob-omb Battlefield. They typically work the same as in the games they officially appear in, making it so Mario becomes a tiny version of himself. In this state, he cannot damage enemies by attacking normally, and now needs to ground pound on the enemies to kill them.
The Mini Mushroom is normally used to pass through tiny gaps, bars, or similar objects in various different levels.
Unlocking Method[]
Some people have reported that they had to unlock the Mini Mushroom in the level Tiny-Huge Island, where the button to unlock the mushroom is on a breakable wall in the tiny island.
Star[]
There have also been reports about a new star appearing in the level Tiny-Huge Island called ''Titan Attack'', in which you have to find a Mini Mushroom in the tiny island to become even tinier, resulting in the enemies becoming three times your size and entirely unkillable. You must avoid them and fit inside a crack in the wall usually close to the Pluck the Piranha Flower star, where the Power Star can be found.
