The Cascade Zombie appears as a shambling figure draped in rotting fabric and creek vegetation, with water constantly streaming from its decomposing form. Its movements are slow but relentless, and it can emerge from any cascading water feature on the course when fog density reaches sufficient levels. The creature leaves wet, muddy footprints that never dry and emanates the smell of stagnant water and decay. Its presence causes nearby water to flow backward briefly, defying gravity as it climbs against cascades.

The Cascade Zombie serves as a persistent pursuer that embodies the classic zombie archetype's relentless nature while adding aquatic horror elements to the creature emergence events. It represents the undead consequences of disturbing the creek's ancient resting places and escalates tension through its ability to emerge from multiple water features throughout the course.
