Ian spots movement in the acid pool

The stone, dislodged by Ian when he throws the remnants of his dissolved tie into the acid pool, plops into the liquid and triggers a ripple effect. This disturbance causes a mega-ant to briefly surface with a light flash before ducking out of sight. The stone acts as a catalyst, revealing the hidden threat beneath the pool’s surface and foreshadowing the planet’s dangerous inhabitants.

Before: A loose stone near the edge of the acid pool, unnoticed until Ian’s actions dislodge it.

After: Fallen into the acid pool, now part of the disturbed surface where the mega-ant briefly appeared.
