Power Shrooms

Mario-style power-ups, a full Mario-inspired moveset, a five-level underground dungeon, and an entire Mushroom Kingdom to explore — with four extra dimensions, 100+ enemies and a dozen bosses.

Power Shrooms started as a handful of 3D mushrooms and grew into a big love letter to Mario platformers for Minecraft Forge 1.20.1. Eat a mushroom, put on Mario's cap, jump down a warp pipe, and go stomp some Goombas.

Requires: Minecraft 1.20.1, Forge, GeckoLib 4.8+ Optional: Cobblemon (Pokémon size features), Lootr (per-player loot), Reactive Music, Trials (copper blocks in the dungeon), PokeRider, GottaCatchemall

Power-ups

Mushrooms and flowers are placeable with Shift + right-click, so you can decorate with them too.

The Mario moveset

Put on Mario's Cap (or Luigi's Cap) and you can:

• Triple jump, long jump, backflip, wall jump and wall slide
• Ground pound to smash through blocks, bounce off enemies and trigger ? blocks below
• Jump about 33% higher and fall up to ~7 blocks without taking damage
• Hit ? blocks and ! switch blocks from below

Everything is tunable from the in-game config screen (/psconfig or Mods → Power Shrooms → Config), including a slider for every jump value.

Level blocks

Warp pipes (enter by crouching), ? blocks, coins (100 coins = 1-Up), cannons, checkpoint flags, jump panels, POW blocks, dotted-outline blocks and more.

The Underworld Pipe dungeon

El Tubo del Inframundo is a 128×104×128 dungeon hidden underground, five levels deep: a real maze, flooded mines, a lava lake, a fortress with Thwomps and Boos, and Bowser himself at the bottom. It's protected against shortcuts until you beat him, drops Bowser's Shell and the Super Star, and the purple pipe at the end opens the way to the Mushroom Kingdom.

The Mushroom Kingdom

A whole new dimension ported from Super Mario Mania's World One, with ten biomes: rolling hills, giant mushrooms, Goomba Woods, Pipe Rock Plateau, Cheep Cheep Beach, Dry Dry Desert, the haunted Ruins… and villages of Toad Houses, Yoshi's House, Peach's Castle and floating sky islands.

Dungeons with bosses

• Bowser's Castle — a second, original castle with its own rematch altar
• Larry's Citadel — a 5×5 grid of rooms, linked with warp pipes
• Goomboss's Tree — climb the trunk branch by branch
• Airships — and Bowser Jr.'s airship
• Boom Boom's Fort, the King Bob-omb Tower, buried dungeons, and the pink-gem room

Dungeons stay protected until their guardians are defeated. Chests give per-player loot with Lootr.

Three extra dimensions

Find a coloured warp pipe shrine in the Kingdom:

• The Dark World — floating islands of gloomrock above the void, haunted trees and bone pillars, and the Dark Knight's Keep guarded by Larry the Dark Knight.
• World 2: Dry Dry Desert — endless dunes, quicksand pits that slow and sink you, and the Desert Pyramid.
• The Corrupted Dimension — total silence, corrupted blocks, spikes that bite, and a distant laugh. Its pipe stays sealed until someone survives MX in your world.

Each dimension has its own arrival platform with a pipe back home.

Pokémon size (optional, needs Cobblemon)
