The traps and extras that define this sequel
Nintendo of Europe calls this the ultimate challenge for a Mario fan: tougher layouts, trickier enemies, fierce winds. The All-Stars Player’s Guide adds poison mushrooms, Super Springs, and Luigi’s different jump. This page stays at that level. It is not a complete hidden-block catalog.
Poison mushrooms
The All-Stars Player’s Guide: poisonous mushrooms power-down a Super or Fire plumber and knock out a small plumber. In All-Stars they are drawn blue so you can tell them apart. Nintendo Classics presents the original-style 8-bit game, where poison mushrooms can look much closer to Super Mushrooms. If a mushroom comes out of a block you did not expect, do not assume it is safe.
CONFIRMED effect — All-Stars Player’s Guide; color is All-Stars-specific, not assumed for Nintendo ClassicsWind
Nintendo UK product copy: “new features like fierce winds that blow Mario away.” Nintendo FR matches that line. Wind changes jump distance. Lean into it when it helps a gap; fight it when a landing is tight. PixelQuest is not publishing a per-stage wind table.
CONFIRMED — Nintendo UK / Nintendo FR Lost Levels product pagesLuigi handles differently
The All-Stars Player’s Guide documents Luigi as a higher, more slippery jumper than Mario. That is a Lost Levels two-plumber difference, not USA Super Mario Bros. 2’s four-character picker. Use Luigi when you need extra air. Do not treat him as universally better — the slip is real. Exact block-height numbers differ by remake; this cluster does not publish a chart.
CONFIRMED difference — Super Mario All-Stars Player’s Guide (Luigi jump / slip); numbers not restated as Nintendo Classics factsSuper Spring
The All-Stars Player’s Guide lists Super Springs as a Lost Levels jump aid alongside poison mushrooms. They launch you higher than a normal spring. They are a tool, not a required route. PixelQuest is not mapping every Super Spring coordinate in this pass.
CONFIRMED as an item — Super Mario All-Stars Player’s Guide (“Lost Level Surprises”)World 9
Nintendo Power Vol. 52 treated reaching World 9 as a real Lost Levels feat. Safe rule: if you want World 9, do not use forward Warp Zones — clear Worlds 1–8 in order. Whether reverse warps also lock it on Nintendo Classics is UNKNOWN here. All-Stars continues from World 9 into letter worlds; original-style copies loop or exit differently. Do not mix those endings.
CONFIRMED World 9 exists — Nintendo Power Vol. 52; reverse-warp / ending flow version-specificWorlds A–D (version split)
Letter worlds exist in the original Famicom Disk System game and in Super Mario All-Stars, but they unlock differently. FDS-style: documented as a title-screen unlock after enough World 8-4 clears (commonly eight title-screen stars, then hold A and press Start). All-Stars: A–D continue after World 8 or World 9. Super Mario Bros. Deluxe does not include those letter worlds. PixelQuest has not independently verified the star-count / A+Start combination on the current Nintendo Classics listing. Treat A–D as version-specific.
VERSION-SPLIT — FDS title-screen unlock vs All-Stars sequential vs Deluxe omitted; NSO listing not independently verified hereContinue / lives
Original Disk System continue and life-count behavior is not restated from memory on this page. Nintendo Classics also adds Rewind (ZL + ZR) on the NES app — that is an app feature, not a 1986 mechanic. PixelQuest is not publishing a continue code or starting-life claim without a booklet line in this pass.
UNKNOWN in this cluster — continue / starting lives not shipped; Rewind is Nintendo Classics chromeWhy this is not a complete secrets farm
A full poison-block list or warp-pipe coordinate dump is low-maintenance only if it is version-locked. This cluster ships the searches players actually make (poison, wind, Luigi, reverse warps, World 9, A–D caveats) and leaves the rest UNKNOWN rather than inventing a catalog.
