  Inspired by the recent observation of new $\Omega_c^0$ states by the LHCb
Collaboration, we explore the excited $\Omega_{c}$ states from the pentaquark
perspective in the quark delocalization color screening model. Our results
indicate that the $\Omega_c(3185)$ can be well interpreted as a molecular $\Xi
D$ predominated resonance state with $J^P=1/2^-$. The $\Omega_c(3120)$ can also
be interpreted as a molecular $\Xi_c^* \bar{K}$ state with $J^P=3/2^-$ and a
new molecular state $\Xi^*_c \bar{K}^*$ with $J^P=5/2^-$ and a mass of 3527 MeV
is predicted, which is worth searching in the future. Other reported $\Omega_c$
states cannot be well described in the framework of pentaquark systems in
present work. The three-quark excited state, or the unquenched picture may be a
good explanation, which is worth further exploration.
