Squeaky Pufts consume Chlorine and produce Bleach Stone, which in the game will turn back into chlorine as it evaporates. Meaning that you can essentially feed the Squeaky Pufts with their own excrement, which is kind of convenient.
What I don't know is whether this creates a net surplus or loss of chlorine/bleach stone. Perhaps it is chlorine neutral even. But if it is a net positive then its essentially a means to produce chlorine.
Can Squeaky Pufts provide a net increase of bleach stone and chlorine?
