What Does The Mystery Key Do In Undertale

So, you've stumbled upon a peculiar item in the quirky world of Undertale: the Mystery Key. It's got a name that screams adventure, doesn't it? But what secrets does this little key actually unlock?

Forget epic boss battles or hidden pathways to new lands. Prepare for something… much cozier. The Mystery Key opens a single room, and that's it.

The Truth Behind the Door

Remember Sans, the skeleton with a penchant for puns and a laid-back attitude? Well, the key opens up a part of *his* house. Specifically, a locked bedroom in his house.

You’ll find the residence easily enough in Snowdin Town. Head right from the entrance until you find Sans’ house.

What's Inside? (Spoiler: It's Hilarious)

Don't expect treasure chests overflowing with gold or ancient artifacts that reveal the secrets of the universe. Inside, you'll find… a treadmill.

And a completely empty room. Yep, that’s pretty much it. Anticlimactic, right? It’s also pure *Undertale* genius.

The real reward isn't the contents of the room. It's the humor. Toby Fox, the creator of Undertale, loves to subvert expectations, and this is a prime example.

It’s a joke. It is a funny joke. It's meant to make you laugh and question the very nature of video game rewards.

The treadmill is likely another rib. Is Sans secretly working out when we are not around? The mystery remains unsolved!

More Than Just a Joke

While the Mystery Key's primary purpose is comedic, it also hints at something deeper. It suggests that even seemingly significant items or quests can have simple, even absurd, solutions.

This reinforces Undertale's overall message. The game frequently encourages players to look beyond the surface and find meaning in the unexpected.

The empty room and the treadmill? They're a reflection of Sans himself. He appears lazy and unambitious but harbors hidden depths.

He uses the empty room as his getaway for self reflection. Who knows! Maybe he does.

He’s definitely working out on the treadmill though. He needs to keep his bones strong!

"The greatest treasure isn't always what glitters."

How to Get Your Hands on the Key

Acquiring this magical Mystery Key requires a little bit of spending. You can buy it from the shopkeeper in Snowdin Town.

The key will cost you 120 gold. Cheap for such a great prize!

Once you have it, return to Sans’ and Papyrus’ house and you can now enter Sans’ secret room! Good luck!

It’s a cheap and silly little adventure that’s worth it.

Embrace the Absurdity

So, the next time you find yourself scratching your head over the Mystery Key in Undertale, remember that not every quest has a grand, earth-shattering conclusion.

Sometimes, the real reward is the laughter and the realization that games, like life, can be delightfully absurd.

Go ahead, unlock that room, hop on the treadmill (figuratively, of course), and appreciate the whimsical genius of Undertale.
