The Headless Horseman is one of the most sought-after prismatic pets introduced during Grow A Garden’s Halloween Event. Known for its haunting presence and rare mutation ability, this spectral rider embodies the perfect balance between aesthetics and mechanical value. Players who managed to hatch it from the Spooky Egg were rewarded with a unique companion capable of altering the game’s pet ecosystem entirely.
Appearance
The Headless Horseman lives up to its name — a terrifying figure with a Jack-O-Lantern for a head, wearing a dark coat with wings, and riding atop a black, fiery horse. The pet emits glowing orange flames that make it stand out even among other prismatic creatures. Depending on its mutation, the visual effects and aura shift dramatically, ranging from spectral blues to radiant golds or corrupted purples.
How to Get It
The Headless Horseman can be obtained exclusively from the Spooky Egg during the Halloween Event.

Trait – The Mutation Master
The Headless Horseman’s signature ability is its power to “haunt” another pet, completely resetting it while granting one of several unique mutations. This mechanic makes it the only pet currently capable of transferring mutation traits — a massive advantage for late-game optimization.
| Mutation | Chance | Effect |
|---|---|---|
| Dreadbound | Common | Grants an additional 6–30 XP per second. |
| Soulflame | Common | +60% XP rate. Occasionally mutates nearby fruit with the Burnt or rare Flaming effect. |
| Spectral | Common | Boosts pet passive by 1.08x. |
| Nightmare | ~7–12% | Boosts pet passive by 1.22x and enlarges the pet by 125%. |
This combination of RNG and power scaling makes the Horseman both a collector’s dream and a strategic investment for mutation farming.
