While typically a hazard within the Mario series proper, the Poison Mushroom in this datapack is actually a highly useful utility item. Using this purple-capped fungus while under the effects of a power-up removes its effects, restoring it to an item in your inventory once more at the cost of the mushroom itself. However, certain stronger power-ups cannot be removed with the Poison Mushroom.

An ability almost as iconic as Mario himself, the Fire Flower allows the user to throw bouncing fireballs as long as their offhand is empty. Once they make contact with an entity that is vulnerable to fire, it deals damage and ignites them for a second. Fireballs will also ignite blocks of TNT they make contact with.

The cold counterpart to the Fire Flower, the Ice Flower lets the user throw bouncing ice balls with an empty offhand. While they travel slower and less distance than fireballs, they freeze enemies in place upon collision, encasing them in a block of ice and leaving them wide open to attacks.

Hailing from Super Mario Bros. 3, the Super Leaf gives you an adorable set of raccoon ears and tail! The tail isn't just for show, however (the ears are, though); right-clicking with an empty offhand allows you to spin the tail around yourself, which can damage nearby entities and slow your descent in the air. This move can also reflect projectiles to travel towards the player's cursor -- arrows, fireworks, tridents, ghast fireballs, ender pearls, wither skulls(!?), TNT(!?), everything! Perhaps it can even reflect certain... other projectiles?

An infamous power-up from Super Mario Bros. 3, the Frog Suit allows its user to leap high into the sky, as well as swim incredibly fast underwater! You can also breathe underwater indefinitely, can mine blocks underwater unimpeded, and are even prevented from passively sinking! The catch? Your mobility outside of water, despite the increased jump height, is slow and cumbersome, potentially leaving you a sitting duck.*

(*That's not a duck, that's a frog.)

The flagship flight power-up of New Super Mario Bros. Wii, the Propeller Mushroom lets you propel high into the skies with little more than a click! After ascending, you can float down slowly and with grace, or sneak to barrel downwards with remarkable speed, damaging mobs upon contact with the ground!

Hailing from the distant cosmos, the Bee Mushroom allows the user to float like a bumblebee, and sting like a...
uh...
Anyways, beeing under the Bee Mushroom's effects causes you to beecome floatier, and immune to fall damage as well. Pressing right click with an empty offhand allows the user to defy the laws of aviation and fly into the sky, however you can only ascend for a limited amount of time before needing to rest on the ground and recharge. Additionally, the Bee Mushroom makes you uneffected to the stickiness of honey blocks, allowing you to travel across them with unimpeded mo-bee-lity. (Okay sorry, that one was too far.) Just don't be caught in the rain or fall in water, or else the power-up will immediately dissipate.

Coming from the depths of hell (the late New Super Mario Bros. series), the Gold Flower is functionally very similar to the Fire Flower. However, the golden fireballs it creates explode on contact with a wall or entity, which deals splash damage to everything caught within its radius and forcing said mobs to drop gold nuggets. It is insanely powerful, capable of killing most enemies in one fireball, but it is incredibly rare as a result. Additionally, being made of gold, Piglins won't attack you when you have this power-up equipped, and treat the Gold Flower the same as any other gold-related item. At least mobs can't use power-ups, that would be terrifying.

The Mini Mushroom. This bite-sized spore makes its user much smaller and more frail, having only three hearts of health before its game over. However, this change in size also has its own benefits, such as a drastically increased jump height, immunity to fall damage, and the ability to fit into much smaller spaces with ease.

One of the two uncraftable power-ups, the Super Star gives you ten seconds of increased mobility, almost complete invulnerability, and a sparkly rainbow trail. Entities that get to close to you in this state will be immediately slain, with particularly stronger mobs requiring a few touches to do in.

The second uncraftable power-up, the Mega Mushroom has similar effects to the Super Star. However, it also drastically increases the user's size, making even a simple step enough to launch foes into the air. A very efficient mob-killer, but probably not something you want to use in an enclosed space.
