Replying...
Intro. She didn't last long as a tunnel runner, having died on her first day electrocuted not far away. Afterwards, she is the first ghost Ula encounters and is frequently re-encountered due to Ula's persistent presence. In her new ghost form, she is labeled a "Low Tier Shocker", chasing the player, trying to hit them with her wrench, and emitting arcs of electricity in all directions. Near the end, she becomes a "High-Tier Shocker", increasing the speed and aggression of her attacks by a large amount and gaining the ability to spread lightning across the entire stage.
