  Interpreting the diphoton mass excesses near 750~GeV reported by ATLAS and
CMS as pseudoscalar gluinonia, bound states of two gluinos, we perform a scan
in Next-to-Minimal Supersymmetry parameter space, fixing $m_{\tilde{g}}\approx
380$~GeV and identifying an experimentally viable point. We generate events
with this point, perform fast simulation, and carry out an analysis modeled on
the ATLAS search which reproduces features of the diphoton excess. This
interpretation requires an enhancement of the signal strength above the nominal
rate found in the literature and neglecting the gaugino mass unification
constraint $M_{3}\approx 3M_{2}$.
