“This is the final challenge. Clear it, and you'll be a truly amazing player!”

—Opening message tip,Super Mario Bros. Wonder

The Final-Final Test Badge Marathon is the final course in theSpecial World and, consequently, the final course ofSuper Mario Bros. Wonder. It features many challenges that require the use ofbadges. BeatingThe Final Test Wonder Gauntlet unlocks a path from there to this level, but only if the player has collected allWonder Seeds,10-flower coins, andgolden flags available so far, and has clearedThe Final Battle! Bowser's Rage Stage. It is the equivalent toSuper Mario Galaxy 2'sGrandmaster Galaxy,Super Mario 3D Land'sSpecial 8-Crown,Super Mario 3D World'sChampion's Road, andSuper Mario Odyssey'sDarker Side, being designed to be the most challenging level in the game. This course features a single Wonder Seed, and completing the course along with collecting all 10-flower coins and reaching the top of the Goal Pole unlocks the final Poplin houseWONDER?. This level's Wonder Seed, 10-flower coins, and top of the Goal Pole do not count towards their respective medal requirements on the player's save file. This is the only Special World level without aWonder Effect, as well as the only level in the Special World to featureCheckpoint Flags.

Unlike Badge Challenges, this is a regular level, meaning the player loses a life normally when defeated and is sent back to the beginning or the last checkpoint, but keeps 10-flower coins collected up to that point unless the level is exited before being cleared.

Layout[edit]

The level takes place in a factory resembling the courses found inCastle Bowser. It is split into a series of rooms separated bypipes; each room automatically changes the player's current badge to a certain Action Badge or Expert Badge, and the player must use said badge to navigate the obstacles in the room. There are a total of 10 rooms, and the level features twoCheckpoint Flags.

The first room uses the Parachute Cap badge, and the player must use it to dodgeSugarstars while activatingWow Buds to lower thepoison until reaching safe ground. The second room uses Floating High Jump, and the player mustjump andGround Pound to propel an accordion-likelift while avoiding large poison geysers. The third room uses Dolphin Kick, which allows the player to dash away from underwaterElectricity Blocks that activate quickly. Clearing this room leads to the first Checkpoint Flag.

The fourth room uses Crouching High Jump, where the player must quickly charge and activate its ability quickly alongZip Tracks to avoid poison geysers andMunchers. The fifth room uses Wall-Climb Jump, where the player must outrun rising poison by using the ability and jumping on the seeds fromMelon Piranha Plants, whileLi'l Sparkies andHotheads move across platforms. The sixth room uses Spring Feet, and requires navigating increasingly thin platforms with large and rapidly movingFire Bars while subject to jumping perpetually. Clearing this room leads to the second Checkpoint Flag.

The seventh room uses Jet Run, requiring the player to repeatedly jump in mid-air after running off platforms, followed byMissile Megs, causing the player to move at an extremely high speed, and finally platforms that slope upward, which changes the trajectory of running off their edges. The eighth room uses Boosting Spin Jump, necessitating that the player use it to prevent themselves from falling into abottomless pit, navigate tight corridors ofSpike Traps, and latch back onto a Zip Track. The ninth room uses Grappling Vine, so that the player can latch onto small walls surrounded by Spike Traps and climb alongHot-Hot Rocks while they are not emitting magma. The tenth and final room uses Invisibility; while being invisible, the player must jump acrossSankaku Trampolines, a magentaBloomp launched to the right from a pump, and several green Bloomps approaching from the right. To aid the player in discerning their location, manyclouds are present in this room, which disappear when the player comes into contact with them. The end of this room has a staircase ofHard Blocks and a final Sankaku Trampoline leading to theGoal Pole, where the Wonder Seed is obtained.
