I think I'm stuck in the same place and can't figure out what I am missing. I have the seed, the fish, and the cover. I took the carrot, used the mushroom, and searched the body. I can't figure out what to do next or how to clean the fish. I think I need the micro microalgae but can't figure out how to get it. Do I need Cesium from the nuclear winter site? If so, I have no idea how to get it. Any suggestions on what I should do next?
