Say, what do we know of spore-based reproduction as of the current version?
Since the raws on the wiki say they have female and male plump helmet men. But it called them castes... Whereas in previous versions that term wasn't used to differentiate the sexes in the raws. That just a universal change for the 2010 version? But that the babies are size 0, is that vermin/invisible size or something that'd be appropriate of spores, or is that just the size babies are so they can be inventory items like for dorfs?
Something I just noticed, they have [MULTIPLE_LITTER_RARE]. Some part of me just keeps telling me that [MULTIPLE_LITTER_RARE] is quite inappropriate for them. Fungal reproduction is one of the lowest form of parental investment in terms of reproduction due to just putting out large numbers of hardy, small spores. Plants get more support from their parents due to the way seeds work. Well, unless they're from spore-producing plants. Then I can't recall what differences exist between the spores other than in activation keys and behaviors.
Someone needs to corral (possibly in one side of a pair of some sort of airlock separated enclosures so that they can be moved to see if spores are left behind that'll become plump helmet men) some without eating them (blasphemous as it is, it must be done for SCIENCE!) in order to see whether they spread spores which grow into babies or if the babby plump helmet men emerge from parental plump helmet men.
