  We present a mechanism for $\Omega_c \to \pi^+ \Omega(2012)$ production
through an external emission Cabibbo favored weak decay mode, where the
$\Omega(2012)$ is dynamically generated from the interaction of
$\bar{K}\Xi^*(1530)$, $\eta\Omega$, with $\bar{K}\Xi$ as the main decay
channel. The $\Omega(2012)$ decays later to $\bar{K}\Xi$ in this picture, with
results compatible with Belle data. The picture has as a consequence that one
can evaluate the direct decay $\Omega_c^0 \to \pi^+K^- \Xi^0$ and the decay
$\Omega_c^0 \to \pi^+\bar{K} \Xi^*$, $\pi^+\eta\Omega$ with direct coupling of
$\bar{K}\Xi^*$ and $\eta\Omega$ to $K^- \Xi^0$. We show that, within
uncertainties and using data from a recent Belle measurement, all these three
channels account for about (12-20)\% of the total $\Omega_c \to \pi^+K^- \Xi^0$
decay rate. The consistency of the molecular picture with all the data is
established by showing that $\Omega_c \to \Xi^0 \bar{K}^{*0} \to \Xi^0K^-
\pi^+$ together with $\Omega_c \to \pi^+ \Omega^* \to \pi^+K^- \Xi^0 $ account
for about 85\% of the total $\Omega_c \to \pi^+K^- \Xi^0 $.
