Key takeaways
- Michal Shafrir, a Sonic developer and superfan, created an interactive Pumpkin Hill costume from Sonic Adventure 2 featuring a working radar and hidden Master Emerald.
- The costume includes jack-o-lantern shoulderpads, an orange and purple corset, platform pieces from the stage, and a radar necklace that responds with hot-and-cold feedback.
- This project escalates Shafrir's prior work from two years ago, when she cosplayed an entire different Sonic Adventure 2 level with a giant truck headpiece.
Michal Shafrir has established herself as someone who takes Sonic the Hedgehog fandom to places most enthusiasts would never consider. A developer on the April Fools visual novel The Murder of Sonic the Hedgehog and self-described Sonic superfan, Shafrir has now completed an interactive costume based on Pumpkin Hill, the treasure-hunting stage from Sonic Adventure 2 where Knuckles the Echidna searches for pieces of the Master Emerald. The Dreamcast classic’s spooky aesthetic naturally fit a Halloween costume, but Shafrir’s approach transformed what could have been a simple visual recreation into something with functional gameplay mechanics.
From Visual Concept to Wearable Level
The costume translates Pumpkin Hill’s stage design into fabric and crafted components. Jack-o-lantern shoulderpads frame a corset bearing the level’s signature orange and purple sky, while the skirt incorporates platform pieces modeled after the floating islands Knuckles navigates during his treasure hunt. A Knuckles figure sits on Shafrir’s shoulder, and at first glance, this alone would constitute an accomplished cosplay. The detail work—matching the autumn pumpkin theming, the vibrant colors, the silhouette of the level itself—accomplishes solid visual translation.
The Visual Design
The jack-o-lanterns serve dual purpose: they reference both the Halloween holiday and Pumpkin Hill’s spooky branding. The orange and purple corset grounds the color palette of the stage itself, preventing the design from drifting into generic autumn territory. The platform pieces dangling from the skirt aren’t merely decorative—they directly reference the geometry players navigate while controlling Knuckles, maintaining accuracy to the actual level layout.
Interactive Gameplay Built Into Clothing
What distinguishes this costume from typical game-inspired cosplay is the functional mechanic woven into its structure. Shafrir crafted a radar necklace modeled after the treasure-hunting interface players use in Knuckles’ levels. Holding the Knuckles figure and moving it around the dress causes the radar to respond with hot-and-cold feedback, guiding the person holding it toward a Master Emerald hidden inside one of the platform pieces. The costume operates as a miniaturized, wearable version of the actual gameplay loop.
How the Radar Mechanic Works
The necklace isn’t decoration—it functions as an actual searching tool. The hot-and-cold response system mirrors the sensory feedback that guides players through Knuckles’ treasure hunts in the original game. Someone moving the Knuckles figure around the dress experiences the same hunt-and-discover rhythm that defines this stage, translated into costume interaction rather than controller input.
Building on Prior Costume Success
Two years ago, Shafrir cosplayed another Sonic Adventure 2 level, based on the truck-chase stage. That costume featured the giant truck that chases Sonic during the stage’s signature sequence, mounted as a headpiece. The truck costume already set an extraordinarily high bar for game-level cosplay—few people attempt to wear an entire stage rather than a character. Shafrir’s current project raises the ambition further by combining level recreation with interactive gameplay elements.
The Timeline
Shafrir has been documenting the costume’s construction process since August, sharing progress updates throughout the months-long build. The project reached completion just in time for Halloween, ready for its real-world debut on Saturday.
Why Pumpkin Hill
Natural Fit for Halloween
The stage’s visual aesthetic and thematic elements made it naturally suited for Halloween costume purposes. Pumpkin Hill stands as one of Sonic Adventure 2’s most recognizable and visually distinct stages, instantly identifiable to fans of the 2001 Dreamcast game. The pumpkins, the autumn atmosphere, and the spooky branding aligned perfectly with the holiday context while remaining faithful to the source material.
Mechanic-Driven Design
The choice also reflected Shafrir’s ambition to move beyond visual recreation. Rather than simply recreating the stage’s appearance, she chose a level whose core mechanic—hunting for hidden treasures with radar guidance—could be translated into an interactive costume element. The treasure hunt that defines Knuckles’ journey through Pumpkin Hill became the blueprint for how visitors would engage with the costume itself.
Interactive Cosplay as Rarity
Most video game cosplay prioritizes visual accuracy and construction difficulty, with creators achieving impressive feats of engineering and design work without necessarily adding functional elements. Shafrir’s approach bridges costume and game mechanic, allowing others to engage with Pumpkin Hill not as a static visual recreation but as an interactive experience. The costume doesn’t just represent the stage—it lets people play a simplified version of the treasure hunt that defines it.
