Beans piss bulb

From 2speccers2tools wiki

The beans piss bulb evolved because there were basically literally no flora on Beans. Their alternate common name is "the piss bulb which must logically exist on beans to maintain a biosphere", but nobody uses that. instead of floating away the balloon just has a long stalk and small leaves that lighter-than-air balloon gas holds up for better photosynthesis. they have modified their spores to be produced from the tips of their lower leaves.
