  In earlier works, we studied the validity of Extended Effective Field Theory
of Inflation (EEFToI) in the regime where initial conditions are set with
dispersion relations $\omega^2 \propto k^6$. We had also evaluated and examined
the power spectrum for some interesting corners of the parameter space. In this
paper, we compute the bispectrum in the EEFToI, take a closer look at the
strong coupling constraints and calculate the size of the non-Gaussianities in
those regions of parameter space. We also investigate the shape of triangles
that contribute to the enhancement of non-Gaussianities in this regime. We find
that there are allowed parts of parameter spaces where EEFToI description with
initial conditions set with $\omega^2 \propto k^6$ is sensible and interesting.
