The properties of a new possible class of events, characterised by large hadronic densities and very few clans, in proton-proton collisions at LHC energy are explored within the mechanism of the weighted superposition of different substructures. The most surprising feature is the appearance of an ``elbow structure'' in the high multiplicity tail, leading to very large expected multiplicity fluctuations.
