I still remember the first time I stumbled upon an Ulcerated Tree Spirit in the depths of Stormveil Castle. The ground erupted, and this writhing mass of roots, pus, and flailing limbs emerged, filling the room with a sense of dread I hadn’t felt since I played Dark Souls 3. There was something oddly familiar about its chaotic movements and the way it used its body as a weapon. It turns out my gut feeling wasn’t wrong. In 2024, a bombshell discovery by data miners finally connected the dots between Elden Ring’s most frustrating field boss and a seven-year-old mystery from Dark Souls 3. That revelation not only satisfied my curiosity but also gave me a newfound appreciation for how FromSoftware recycles and refines its ideas.

The SnakeSoul That Never Was
Long before Elden Ring ever became a twinkle in Hidetaka Miyazaki’s eye, data miners were already tearing apart Dark Souls 3’s files. Among the countless unused assets, one enigmatic label kept resurfacing: "SnakeSoul." This entity was linked to the Pus of Man enemies – those terrifying abyssal serpents that burst out of hollows – but it was clearly intended to be a full-fledged boss. For seven years, the community speculated about what SnakeSoul could have looked like. Some believed it was an early version of Oceiros or the King of the Storm, while others thought it was simply a scrapped variant of the Pus of Man. The truth, however, was being kept alive in a different game.
The AI Name That Gave It All Away
The breakthrough came when YouTuber and data miner Zullie the Witch dug into Elden Ring’s internal files. While examining the Ulcerated Tree Spirit, a boss that has given every Tarnished at least one rage-filled afternoon, Zullie discovered that its AI identifier is none other than "SnakeSoul." This wasn’t a coincidence or a leftover asset name reused randomly. The behavior patterns, the serpentine thrashing, and the ability to spew corrupted matter all align perfectly with what one would expect from a creature born from the Pus of Man lineage. How could FromSoftware keep this secret for so long, hiding a cut Dark Souls 3 boss in plain sight within their new masterpiece? It’s genius, really – taking an idea that never fully hatched and giving it a second life in a world where it finally makes sense.
Visual Proof Hidden in Ancient Footage
If the AI name wasn’t convincing enough, the mystery deepened when fans revisited some very early Dark Souls 3 promotional material. In one of the original gameplay trailers, a fleeting shadow can be seen stretching across a wall – a shadow that, upon close inspection, mirrors the silhouette of the Ulcerated Tree Spirit almost exactly. The elongated neck, the coiled lower body, and the erratic jerkiness are all there. I can’t help but wonder: did FromSoftware actually complete a prototype of SnakeSoul back in 2016, only to cut it because it clashed with the game’s pacing or lore? Or was it always meant to be resurrected later when the technology and artistic vision aligned? Either way, seeing that shadow made me realize just how long this serpentine terror had been waiting in the wings.
FromSoftware’s Philosophy of Recycling Nightmares
This discovery isn’t just a fun piece of trivia; it reveals a profound design philosophy that I’ve come to admire. FromSoftware doesn’t throw away good ideas – they store them like seeds, planting them in new soil when the right project comes along. The Ulcerated Tree Spirit fits perfectly into Elden Ring’s themes of decay and the corrupted Erdtree. Its visual language, mixing wood, flesh, and abyssal energy, feels like a natural evolution of the Pus of Man concept. But did you ever consider how many other cut bosses might be lurking in future titles? Perhaps the infamous "Great One Beast" from Bloodborne’s chalice dungeons will one day rear its head in a futuristic Armored Core game. With FromSoftware, the only limit seems to be time.
The Community’s Reaction and My Own Aha! Moment
When the video dropped in 2024, the Souls community erupted. Veterans who had spent years debating SnakeSoul’s identity finally had their answer, and newcomers to Elden Ring suddenly understood why this optional boss felt so distinct compared to all the other overworld encounters. I myself went back to fight the Ulcerated Tree Spirit in the Fringefolk Hero’s Grave with fresh eyes. Every lunge, every sweeping attack, and every gurgled roar now carried the weight of a decade-long secret. It made the fight feel like a treasure hunt within a treasure hunt. Could there still be undiscovered connections like this waiting in the Lands Between or in the Realm of Shadow? With the massive DLC now a couple of years old, data miners are still finding fascinating things, and I wouldn’t be shocked if another Dark Souls relic surfaces eventually.
What This Means for Future Games
As we move into 2026 and look ahead to whatever FromSoftware is cooking up next, this SnakeSoul revelation has taught me to pay attention to every misplaced shadow and every strangely named file. The studio’s willingness to let ideas simmer for years before implementing them gives their games a timeless quality. The Ulcerated Tree Spirit is no longer just another giant health bar to overcome – it’s a bridge between worlds, a testament to the fact that in game development, nothing truly dies. Next time you encounter one of these festering horrors thrashing about in a cramped room, ask yourself: what other horrors did FromSoftware hide in this creature’s code? And what amazing nightmares are they holding back even now, waiting for the perfect moment to unleash them upon us? I know I’ll be listening to every squelch and shriek a little more carefully from now on.
