Power Shrooms

New dimensions

• The Dark World (powershrooms:dark_world): floating gloomrock islands over the void with dark-matter cloud underneath, haunted trees, bone pillars, ash in the air, green-blue fog and a "-< Dark World >-" title on arrival. Home of Boos, Dry Bones, Bone Goombas, Bony Beetles and Fuzzies.
• World 2: Dry Dry Desert (powershrooms:world_2): yellow-sand dunes over desertstone, with the Kingdom's desert enemies and structures.
• The Corrupted Dimension (powershrooms:corrupted_dimension): corrupted ground, total silence, an occasional distant laugh, corrupted blocks, MX pillars and buried dungeons. Only MX and "He" live here. Its pipe stays sealed until someone survives MX in that world.
• Each dimension has an arrival platform with a welcome chest and a return pipe; every player returns to the pipe they entered through.
• Access is through coloured warp pipe shrines in the Mushroom Kingdom: yellow (desert), black (Dark World), red with glitches (Corrupted). Shrines only generate in newly explored Kingdom chunks; the dimensions themselves exist in old worlds too.

New structures and loot

• Dark Knight's Keep: walls, towers, a garrisoned courtyard and Larry the Dark Knight as boss, with two reward chests. Protected until he falls.
• Desert Pyramid: a quicksand-trapped corridor and a six-spawner chamber with two chests. Protected until it's cleared.
• Pink Gem Room in the Corrupted Dimension, plus quicksand pits in the desert.

New blocks

• Quicksand (yellow and dark): no collision; slows you, sinks you slowly, gives Mining Fatigue, and blinds you if your head goes under. Dark quicksand sinks faster and hurts. Push against an edge to wade out.
• Corrupted spikes: 4 damage and Slowness II.
• 56 new blocks: gloomrock family, haunted wood (with door, trapdoor, fence and gate), darkore, bone, dark matter, desertstone, corrupted blocks, the crimson gem and stone torches.
• New desert, dark and corrupted warp pipes.

60+ new enemies and creatures

• Goomba family: red, bone, big and mega Goombas, Paragoomba. Goombas now stack into towers.
• Sea: Deep Cheep, Eep Cheep, Para Cheep Cheep, and the three-piece Unagi eel.
• Dungeon enemies: Fire Bro, Enraged Bully, Elite and Melon Piranha Plants, Elite Spiny, Rubbery Bulb.
• Creatures with tricks: Maw-Maw (eats Goombas, can become your friend), Shellslug, Skedaddler, Vegy, Woodbug, Mad Piano.
• Koopa the Quick: race to a flag for a Super Star.
• MX (a once-per-world horror chase) and He, who watches from afar afterwards.
• Larry the Dark Knight — a new boss.
• Fauna: Sleepy Sheep, little birds, Rainbow Fairy, Money Bag and the December-only Gifthopper.
• Volcano Lotus block that spits spores in Mole Hills and the Goomboss's Tree.
• Dungeons no longer use stand-in enemies: every spawner now spawns the real thing.
• Cheep Cheeps no longer spawn green at random (that look is now the Deep Cheep).

Changes and fixes

• Rolling Koopa shells now vanish after 20 bounces (previously they stopped after 30 and sat there).
• Captured bosses fight for you. Bowser and the other bosses, when captured with GottaCatchemall, no longer stay locked to their arena: they follow their owner, fight anywhere, and don't open dungeon pipes or play boss music when "defeated".
• Updated art for many existing Kingdom blocks (clouds, mushroom grass and more), a few English names fixed, and the muncher block can now be mined with a pickaxe.
