Bioluminescent snipers of the hallowed night
Gastropods are floating predatory mollusks that hover over Hallowed surface fields during the night. Their translucent, glowing shells illuminate the darkness while they scan for prey from elevated positions. Possessing 220 health and 22 defense, they prefer to maintain distance, hovering gently in the air while taking aim with high-precision light attacks across fields and meadows.
Evading laser bursts and gathering glowing gel
Rather than engaging in close quarters, Gastropods fire luminous pink laser blasts that travel at high velocity, inflicting 60 damage in Classic and 120 in Expert. Slaying these floating snipers yields Gel at a 100% rate in stacks of 5–10, alongside delicious Chocolate Chip Cookies at a 1.33% rate to grant food bonuses.
Trivia
- Gastropods emit dynamic light in the dark, making them visible from great distances.
- Their laser attacks travel in straight trajectories with virtually no projectile drop.
