An annual pairing ritual occurs in Yzore communities. Neblitzi springboks propel themselves upstream, toiling against the current to arrive at the encampment of Salivrasters, who have unfailingly forgotten about the whole thing and are caught completely by surprise. Then, one by one, the Salivrasters wade into the stream and pluck a Neblitz by antenna, and the two become mates for life. (The Neblitz never stops grumbling that the Salivraster could easily have made the short walk downstream.)
