You actually don't have to dig nearly as deeply as you might think you do in order to find the inherent weirdness in the world of Mario games. For starters, Mario is a plumber who used to be a construction worker and is also sometimes a doctor. His brother is Luigi, who sometimes is his identical twin and other times is slimmer and a foot taller than Mario. The love of his life is the princess of a land of mushroom people who are constantly being terrorized by a bipedal, turtle-esque beast and his turtle army who have wings and throw hammers and some of which may or may not be his children.

In all seriousness—such as seriousness is going to exist in this list—the Mario games definitely get weird beyond just the general fantastical strangeness of their basic world and premise. When a game character has been around for nearly 40 years, and has evolved to be the all-purpose Mickey Mouse of his company, there are bound to be a lot of bizarre facets to his legacy. While things obviously go off the rails on the rare occasion that Nintendo has let another company take a crack at Mario, even within the games developed in-house there are a lot of really wacky adventures that Mario has gone on. And don't think for a second that the core Super Mario series of platformers is exempt from that, either.

Just to mix things up a bit, though, we're going to also include some Mario games that deserve a remake in this list. We wouldn't want you to have weirdness overload.

30 Weird: Hotel Mario

via Know Your Meme

It's hard to fathom now, but there was a (very) brief period when another company had the rights to develop and publish Mario and Zelda games with zero input from Nintendo. The results were almost universally terrible, of course.

Hotel Mario's actual gameplay mechanics aren't completely broken, they are just utterly boring: a puzzle game revolving around opening and closing doors. But it's the abysmal animated cutscenes that look like they were done in two hours by a team of five-year-olds that is the most perplexing thing about this shameful release.

29 Weird: Mario + Rabbids Kingdom Battle

We never said that all the weird games on this list were going to be bad—in fact, some of them are pretty great, which definitely applies to this family-friendly take on the turn-based strategy genre that is honestly one of the best Switch games so far.

It's not so much the crossover itself that is bizarre, but the Rabbid doppelgängers of the familiar Mario characters.

The Rabbids themselves have always been strange, but to see them enter the Mushroom Kingdom and interact with Mario and company is as jarring as it is hilarious.

28 Weird: Super Mario Bros. 2 (U.S.)

via Emuparadise

While it is many people's favorite Mario game to this day, there is no way to frame Super Mario Bros. 2 as anything but odd. In fact, its setting, the bulk of its enemies, and most of its mechanics have still yet to return to the Mario series in anything but the tiniest of bursts.

While the game is set in Mario's dreams (kind of) which explains why he and his pals feel so out of place, it still never fully feels like a true Mario game—which is exactly what so many people love about it.

In the mid-90s, Nintendo let various developers of educational software borrow Mario and friends for use in various learning-type video games. One of the results of this deal was the boring PC release Mario's Game Gallery, later ported to Macintosh as Mario's FUNdamentals for some reason.

Essentially a collection of traditional family board games like checkers, Go Fish, and an off-brand Yahtzee knockoff called "Yacht," the Nintendo assets just end up being pointless window dressing on a bland title that does have one neat distinction: it's actually Charles Martinet's debut as the voice of Mario.

26 Weird: I Am A Teacher—Super Mario Sweater

via Giant Bomb

On paper, it's an interesting idea—a video game that lets you design your own custom images for a sweater and have a professional company actually make it for you. But this was 1988, so the entire process was needlessly expensive and cumbersome.

Given its obscurity, it's tough to know for sure just how much freedom you had in your designs in I Am A Teacher: Super Mario Sweater, but we're guessing you probably had to largely just stick to some basic version of Mario's sprite. And at $24 in 1980s money to have the sweater made, it was too cost-prohibitive for mainstream consumers.

25 Needs A Remake: Super Mario Land 2

via Reddit

It's pretty tough to play an original Game Boy game these days. And that is a shame for a release like Super Mario Land 2, since the game itself is well worth revisiting and deserves to be appreciated as much as any other 2D Mario game.

If nothing else, just fully colorizing the game and optimizing it for televisions would go a long way in reviving this fairly forgotten classic.

Ideally, though, Super Mario Land 2 should see some full-on Super Mario All-Stars caliber remake that takes the original's inventive worlds and power-ups and brings them up to modern visual standards.

24 Weird: Mario Is Missing!

via juegosadn.eleconomista.es

Poor Luigi—he had to make his debut as a main character in this strange and completely forgettable point-and-click educational game.

What makes games like Where in the World is Carmen Sandiego? so revered is their ease-of-play. Mario is Missing, on the other hand, is completely obtuse and needless cumbersome, making figuring out how to even play the thing the bigger challenge than finding your missing brother. Worst of all, the developers tried to combine existing Mario assets with their own generic original art, making for a game that lacks any sort of aesthetic cohesion.

23 Weird: Wrecking Crew

via via Neko Random

Mario's "day job" is said to be plumbing—though that really only manifests itself through the pipes present in the games and little else. In his Donkey Kong debut, he was more of a construction worker, which Nintendo actually revisited for the 1985 game Wrecking Crew.

Never is Mario more in "work mode" than he is in Wrecking Crew.

The single-screen game involves Mario destroying various elements of the environment in an almost reverse-Fix It Felix. His look in the game is pretty jarring as well, calling back to Mario Bros. but releasing the same year as Super Mario Bros.

22 Weird: Mario Clash

via reinodocogumelo.com

Everything about the Virtual Boy is weird—that its graphics are entirely red on black backgrounds, that you had to set it up on a table rather than be able to wear it, and that it actually made it to market.

Even weirder is that Mario Clash wound up serving as the main "Mario game" for the platform, a pseudo-remake of the original Mario Bros. set on awkward 3D planes. Why this over a more traditional, modern platformer? It's as if they didn't have much faith in this console or something...

21 Weird: Mario's Bombs Away (Game & Watch)

via bandicam.com

For those that don't know, Game & Watch was a series of LCD devices that doubled as a digital watch and a simple video game (get it?). Each one contained just a single game, and the mechanics were usually of the "easy to learn, difficult to master" school of game design.

While most of them involved innocent tasks like working in a factory, Mario's Bombs Away saw Mario take on the role of a Beetle Bailey-esque soldier in a very obviously Vietnam War-inspired backdrop as he caught bombs thrown from trees. Not surprisingly, this one is never really referenced anymore.

20 Weird: Mario Paint

via YouTube

Consoles have slowly been morphing into PCs for years, and it goes back even further than you might realize. One early bridge between the two worlds was Mario Paint, which actually came with a mouse and turned your SNES into a painting and music composition program.

And there was also a fly swatting mode for some reason.

People continue to do impressive things with Mario Paint to this day, especially its music maker. But it was still on odd little program the likes of which felt out of place on a 16-bit console.

19 Needs A Remake: Super Mario RPG—Legend Of The Seven Stars

via Kotaku Australia

While it may be true that few generations of video games are as timeless from a visual standpoint as 8- and 16-bit games, that isn't true for all graphical styles. That psuedo-3D rendering made popular by games like Super Mario RPGDonkey Kong Country, and Killer Instinct is pretty rough on the eyes today.

That's why Super Mario RPG needs a remake in the style of Donkey Kong Country Returns, which retains the spirit of that original visual style by does it in modern, actual 3D graphics. Sequel or actual remake, it doesn't matter—just make it happen.

18 Weird: Super Mario Land

At first glance, Super Mario Land just seems like a shrunken-down version of a Mario NES game, not unlike a lot of franchises that made the transition from the NES to the Game Boy. But it only takes a few minutes to realize that SML is actually pretty bizarre.

The fireballs go careening wildly all over the screen, enemies explode rather than being kickable, there is a level that is inspired by ancient Egypt, Bowser is out, and there are side-scrolling shmup levels. It feels like a Doki Doki Panic situation, and another game was retooled as a Mario game.

17 Weird: Mario Teaches Typing

via YouTube

Years before Sega's ingenious The Typing of the Dead re-imagined their light gun zombie game as a typing teacher, Mario got in on the act with this offbeat release.

The game is exactly what you'd imagine: you type certain letters as Mario navigates his world avoiding enemies and collecting power-ups.

It's obvious this wasn't an in-house Nintendo production, though, as various elements—like the Koopa Troopas, as seen above—just don't look quite right. And unfortunately, this was only ever released for PC. If they made a mouse for the SNES, why not a keyboard?

16 Weird: Super Mario Sunshine

via Pinterest

The Gamecube saw Nintendo at their most experimental in terms of their games. They turned Metroid into a first-person shooter, they let two players share a kart in Mario Kart: Double Dash, Link became a big-eyed anime child in Wind Waker, and their big Mario game was built entirely around a water-spouting backpack and took place almost entirely in tropical locales.

Super Mario Sunshine is definitely one of the more divisive 3D Mario games, and is more gimmick-based than core Mario games typically are. Think of it as the Super Mario Bros. 2 of 3D Marios.

15 Weird: Donkey Kong Jr.

via IMDb

It's pretty cut and dry in the original Donkey Kong who was "good" and who was "evil"—Mario had to rescue Paulina, who had been stolen by the big ape.

In follow-up Donkey Kong Jr., however, the line between good and bad is much blurrier. Mario has imprisoned Donkey Kong, with Donkey Kong Jr. having to rescue his pops. Sure, DK did some iffy things in the past, but from his son's perspective, some dude has his dad in a cage and he just wants him back. Is this a Mario heel turn?

14 Weird: Mario & Wario

via Hardcore Gaming 101

This is it, a one-on-one showdown between Mario and his evil counterpart Wario...right? No? Then it's a co-op platformer where the two team up! Still no? Then what the heck is this game all about, anyway?

Mario & Wario is actually about some character named Wanda who has to guide a blinded Mario through trap-filled levels.

It's fine for what it is—though Wanda is a bland and instantly forgettable character—but it's not the game anyone would've hoped for given the potential of its title. It's probably for the best it remained a Japan exclusive.

13 Needs A Remake: Mario Kart 64

via 365 Things Austin

Mario Kart 64 remains a fan-favorite entry in the long-running series, but like a lot of N64 games, it's not all that easy to appreciate in 2018. Sure, we've gotten to revisit most of the tracks from MK64 through their inclusion as classic tracks in subsequent sequels, but there's still something about the original game itself that has a certain allure.

The solution? A straight-up HD remaster of Mario Kart 64. Raise your hand if you wouldn't be interested in that. Yep, that's zero hands raised. And then do F-Zero X next.

12 Weird: Mario & Luigi—Bowser's Inside Story

via IGN Africa

The Mario & Luigi series of RPGs have featured some of the funniest writing and most imaginative gameplay in Mario history. From the GBA original to Dream Team—yep, we left out the disappointing Paper Jam on purpose—the Mario & Luigi games have been a consistent treat.

And then there's the installment where you get sucked into Bower's body.

While Bowser being an ally has long been a staple of Mario RPGs, Bower's Inside Story takes that to an extreme with Mario and Luigi literally inhabiting Bowser as they help guide him to victory. In a word: eww.

11 Weird: Super Mario Bros. 2 (Japan)

via GameSpite.net

Before the bizarre American version of Super Mario Bros. 2, there was the bizarre Japanese version of Super Mario Bros. 2. While the American one was an offbeat but  enjoyable romp, Japanese SMB2 was basically SMB1 if it were made by developers who hate you.

While Mario games can get challenging, they are seldom unfair—which can't be said for this game, with poisonous mushrooms, invisible wind gusts over chasms, and warp zones that take you to previous levels. It feels more like a ROM hack designed for people to curse at on YouTube than a polished, enjoyable Mario entry.
