Something pulled my shaving brush plant into a dark cave and ate half of it. It also ate some of my Caulerpa. There is a large brittle star and a Sally Lightfoot Crab in the area. There are no other inhabitants except for a couple Cerith snails, bumblebee snails and Astraea snails, a herd of BTAs and an anemone crab that minds its own business and never leaves its BTA. Which one should I arrest and throw in the dungeon, the SLFC, or the brittle star?
