Edit image 1: keep the two kids, their poses, suits, helmets and lamp beams exactly. Fix the giant jellyfish to match the real Stygiomedusa gigantea of image 2: a DARK burgundy / deep wine-red bell (not pale, not pink, not white), smooth dome with a scalloped rim, about ONE metre across: its bell is about as wide as Kira is tall, so place it a little above the kids at that size; four broad flat ribbon-like dark-red arms trailing down several metres past the kids like silk curtains. It does not glow: it is lit only where the two white lamp beams touch it, and everything outside the beams fades into black water. Soft pale marine-snow flakes drift in the beams. No text.
