Day five, you stop wanting to leave.

But more than that… it likes when you finally stop. Would you like this as a short story, a TTRPG creature stat block, or part of a larger SCP-style file?

Three days post-exposure, you shed your skin in one perfect piece. Your new skin has the same cilia as the bug. You can feel radio waves now. You can hear the island’s magnetic field.

Do not visit Mushijima. Do not research the hum. If you see a spider that walks like a mantis and pulses like a radio tower, do not run.

Its legs are too long, even for a harvestman. Eight of them, yes, but jointed like a mantis shrimp’s club arm. When it walks, it doesn’t step—it unfolds .
