  Unlike the octet baryons for $N_f=3$, there is no skyrmion coming from the
$\eta^\prime$ meson. It is instead described as a fractional quantum Hall
droplet, a pancake or a pita involving a singular $\eta^\prime$ ring in which
Chern-Simons fields live. By incorporating hidden local symmetry and hidden
scale symmetry in nuclear dynamics, I describe how to access baryon-charged
quantum Hall droplets in dense nuclear matter in terms of the nuclear
scale-chiral effective field theory approach ``G$n$EFT" with the $U_A(1)$
anomaly taken into account. I discuss how the single-flavor baryon that I will
call ${\cal B}^s$ could be exposed in superdense baryonic matter, figuring,
perhaps, in ``quark stars" associated with the baryon-quark continuity
involving CFL or phase transitions.
