Sensing danger, the crayfish immediately turns tail and flees back where he came from. You'll have to head back to where you started if you're going to track the troglobite down again.

If you are at The Gastric Mill, discard Furtive Troglobite. Otherwise, return Furtive Troglobite to the collection and permanently move it to the The Gastric Mill set.
