  In the LHC searches for gluinos it is usually assumed that they decay
predominantly into the lightest neutralino plus jets. In this work we perform a
proof-of-concept collider analysis of a novel supersymmetric signal in which
gluinos decay mostly into jets and the bino-like neutralino ($\tilde\chi_3^0$),
which in turn decays into the lightest Higgsino-like neutralino
($\tilde\chi_1^0$), considered the dark matter candidate, together with the
SM-like Higgs boson ($h$). This new physics signal then consists of an LHC
final state made up by four light jets, four $b$-jets, and a large amount of
missing transverse energy. We identify $t \bar t$, $V$+jets ($V$= $W$, $Z$),
and $t \bar t + X$ ($X$ = $W$, $Z$, $\gamma^*$, $h$) productions as the most
problematic backgrounds, and develop a search strategy for the high luminosity
phase of the LHC, reaching signal significances at the evidence level for a
luminosity of 1000 fb$^{-1}$. The prospects for a luminosity of 3000 fb$^{-1}$
are even more promising, with discovery-level significances.
