A growing neutrino mass can stop the dynamical evolution of a dark energy scalar field, thus explaining the "why now" problem. We show that such models lead to a substantial neutrino clustering on the scales of superclusters. Non-linear neutrino lumps form at redshift z approximate to 1 and could partially drag the clustering of dark matter. If observed, large scale non-linear structures could be an indication for a new attractive "cosmon force" stronger than gravity.
