Sprunki Kick the Buddy — Ragdoll Simon Castle is a fan-made browser-based stress-relief mod that places Simon, the iconic yellow Sprunki character from the Incredibox Sprunki universe, into a medieval castle arena as the central ragdoll target. The mod belongs to the broader Sprunki Kick the Buddy family — a series of community-created experiences that replace the original Kick the Buddy dummy with recognizable Sprunki characters — but distinguishes itself through its castle-themed environment, Simon-specific ragdoll physics, and phase-reactive visual system.
The experience runs entirely in-browser via HTML5, requiring no downloads or installations. It is hosted on fan platforms such as Castle.xyz and various Sprunki mod aggregators. The core loop is simple: attack Simon with an arsenal of weapons, watch him react through exaggerated ragdoll physics, earn coins through combos, and unlock new tools and cosmetic options. There are no levels, no timers, and no failure states — just pure, pressure-free catharsis.
Note: "Ragdoll Simon Castle" is treated here as a specific variant within the Sprunki Kick the Buddy ecosystem. The description below synthesizes mechanics shared across the Simon-targeted Kick the Buddy mods and the Castle-hosted Sprunki interactive experiences.
The gameplay is designed for instant accessibility. No tutorials, no progression gates, no paywalls blocking core features.
Open the mod in a supported browser. The screen loads directly into a medieval castle interior — stone walls, arched doorways, torch-lit corridors, and a central stage area where Simon stands waiting. The environment is fully interactive, with hazard zones, destructible props, and environmental triggers scattered throughout.
A weapon panel sits at the bottom or side of the screen. Available tools include:
Melee: hammers, baseball bats, chainsaws, sledgehammers
Ranged: rocket launchers, water cannons, laser rifles
Explosives: TNT, grenades, explosive barrels
Special: freeze rays, UFO tractors, slingshots, flamethrowers
Environmental: anvils, spike traps, electrified floors, lava pits
Absurd: rubber chickens, disco balls, feather dusters
Each weapon produces distinct visual effects, sound feedback, and ragdoll reactions. Hover over items to preview their sounds before committing.
Click or tap anywhere on Simon to punch, slap, or interact. Drag and drop weapons from the toolbar directly onto him to unleash their effects. Swipe or hold to charge stronger attacks like powerful kicks or explosive throws.
Simon reacts dynamically:
Spins when hit with rotational force
Deforms temporarily under heavy impact
Explodes into ragdoll fragments when hit with explosives
Changes facial expressions based on the current Phase
Flies across the arena based on force, angle, and physics simulation
Chain attacks together to build a combo multiplier. Higher combos earn more in-game coins, which unlock:
New weapons
Cosmetic outfits for Simon
Alternate background themes
Special effect modifiers
The combo system rewards creativity over repetition — mixing weapon types and timing produces higher multipliers than spamming a single tool.
The mod features a multi-phase system where Simon's appearance and behavior change depending on the active phase:
| Phase | Visual State | Behavior |
|---|---|---|
| Phase 1 | Calm, friendly yellow Simon | Standard ragdoll reactions |
| Phase 2–4 | Progressively more aggressive expressions | Faster reaction animations, altered facial states |
| Phase 5 / Sprunded Mode | Heavily distorted, Teimu-style Simon | Extreme visual and audio distortion |
Use the phase selector (typically located in the top corner) to switch between states. Each phase changes Simon's appearance, facial expressions, and sometimes his reaction speed.
If you want to restore Simon to his original state, use a medkit from the toolbar. This resets his visual condition without clearing your combo or coin progress. If Simon gets stuck in geometry, use the reset button in the top-right corner to respawn him at center stage.
Unlike the Incredibox-based Sprunki mods that focus on layered musical composition, the audio identity of Ragdoll Simon Castle is built around impact-driven, phase-reactive sound design.
| Element | Description |
|---|---|
| Impact sounds | Punchy, exaggerated hits that scale with weapon type and force |
| Ragdoll physics audio | Collisions with walls, floors, and props produce distinct crash and bounce sounds |
| Weapon feedback | Each tool has a unique activation sound — chainsaws rev, rockets whistle, freeze rays crackle |
| Phase-based audio shifts | Simon's reaction sounds change pitch, distortion, and intensity depending on the active phase |
| Environmental cues | Trap triggers, explosions, and hazard activations carry audio weight |
In the broader Sprunki universe, Simon's canonical voice is an 8-bit electronic synthesizer tone — a bright, chirpy digital sound that serves as his melodic identity in Incredibox Sprunki mods. In the Kick the Buddy context, this sound is repurposed:
Light hits produce short, high-pitched synth blips
Heavy impacts trigger distorted, pitch-shifted versions of the same tone
Phase 5 / Sprunded Mode warps the synth into low, grinding static
Explosions layer the synth tone beneath the blast for a signature audio fingerprint
Most Sprunki mods treat sound as a musical layer — beats, melodies, vocals arranged into compositions. Ragdoll Simon Castle treats sound as physical feedback. The audio is not designed to be composed; it is designed to be triggered. Every explosion, every ragdoll collision, every weapon swing produces a sound that reinforces the tactile satisfaction of the interaction.
The result is closer to a physics-based sound toy than a music game. The chaos itself becomes the soundtrack.
Simon is one of the most recognizable characters in the entire Sprunki ecosystem. His role in Ragdoll Simon Castle draws directly from his established canonical identity.
| Attribute | Detail |
|---|---|
| Full Name | Simon (西蒙) |
| Species | Sprunki |
| Gender | Male |
| Skin Color | Yellow |
| Hair | A single tuft on his forehead, two antennae |
| Ears | Two triangular pointed ears on the sides of his head |
| Eye Color | Black |
| Voice Type | 8-bit electronic synthesizer |
| Role in Sprunki | Melody character; designated by the original creator as the protagonist of Normal Mode |
Simon is characterized as:
Kind, optimistic, and confident in normal mode
A dentist by profession (in Sprunki lore)
One of the fastest runners in the Sprunki cast, alongside Raddy
A chocolate enthusiast with a well-documented sweet tooth
Near-sighted — confirmed by the original creator to wear glasses when reading
A Fortnite player who plays with Oren, Clukr, and Garnold — and is canonically the worst at it
Someone who gets extremely agitated if called "蛋黄触角" (egg yolk antenna)
A character who can drive and finds kissing "mysterious"
Oren — Close friend, part of the "golden trio" with Durple. Not related by blood.
Durple — Close friend, completes the golden trio.
Brud — Complicated. In horror mode lore, Simon bit off half of Brud's head. In normal mode, they are friends.
Pinki — Community interpretations vary; some versions depict a crush dynamic.
Black — Classified as an enemy in canonical character data.
In the original Sprunki mod's horror mode, Simon undergoes one of the most disturbing transformations in the cast:
Eyes completely close, reduced to two dark shadows behind the eyelids
Mouth stretches open to an unnatural width, revealing oversized, realistic teeth
Becomes a biting, lunging creature — the character responsible for Brud's injury
The original creator described this form as Simon having "completely become a monster"
This horror identity carries over into certain phases of the Kick the Buddy mod, where later phases progressively distort Simon's appearance toward his horror form.
The mod adapts Simon's canonical design for the ragdoll context:
Normal phases: Bright yellow body, antennae intact, calm expression, triangular ears visible
Mid phases: Expressions shift to annoyed, panicked, or aggressive
Late phases / Sprunded Mode: Heavily distorted, eyes narrowed or absent, teeth exaggerated, body proportions warped
Ragdoll physics: Full-body deformation on impact — limbs flail, head wobbles, body compresses and stretches
Simon's appearance evolves across multiple phases, each changing his expressions, body language, and reaction animations. This gives the mod a progression feel without traditional levels.
Every hit sends Simon flying based on force, angle, and collision. No two interactions look the same. The castle environment adds walls, pillars, and props for ricochets and chain collisions.
The medieval setting differentiates this variant from other Kick the Buddy mods. Stone architecture, torch lighting, and hazard zones create a distinct visual atmosphere.
Chaining creative attacks earns coins that unlock new weapons, outfits, and cosmetic options. The system rewards experimentation over repetition.
A medkit restores Simon's visual state. A reset button respawns him at center stage. These tools keep sessions flowing without interruption.
No levels, no leaderboards, no saved stats, no paywalls. Every session starts fresh. The mod exists purely as a stress-relief tool.
The Sprunki Kick the Buddy family includes variants targeting nearly every major character — Wenda, Durple, Oren, Mr. Sun, Sky, Pinki, Gray, Sandbox, Tunner, and others. Ragdoll Simon Castle distinguishes itself through:
Simon's canonical status as the protagonist of Normal Mode, giving him narrative weight that other targets lack
The phase system that progressively transforms Simon from friendly to monstrous, mirroring the original Sprunki mod's dual-mode structure
The castle environment, which provides a distinct visual identity compared to the generic arenas of other variants
Simon's rich lore — his relationships, his horror transformation, his personality quirks — all of which add layers of meaning to the act of attacking him
The audio fingerprint of his 8-bit synth voice being repurposed as impact feedback
It appeals to players who want the Sprunki Kick the Buddy formula combined with a recognizable, lore-rich character and a visually distinct setting — a stress-relief sandbox where the target is not just a ragdoll, but a character with history.
