It has been proposed that the gamma ray burst - supernova connection may manifest itself in a significant fraction of core collapse supernovae possessing mildly relativistic jets that do not break out of the stellar envelope. Neutrinos would provide proof of the existence of these jets. In the present letter we calculate the event rate of ~100 GeV neutrino-induced cascades in km^3 detectors. We also calculate the event rate for ~10 GeV neutrinos of all flavors with the DeepCore low energy extension of IceCube. The added event rate significantly improves the ability of km^3 detectors to search for these gamma-ray dark bursts. For a core collapse supernova at 10 Mpc we find ~4 events expected in DeepCore and ~6 neutrino-induced cascades in IceCube/KM3Net. Observations at ~10 GeV are mostly sensitive to the pion component of the neutrino production in the choked jet, while the ~100 GeV depends on the kaon component. Finally we discuss extensions of the on-going optical follow-up programs by IceCube and Antares to include neutrinos of all flavors at ~10 GeV and neutrino-induced cascades at ~100 GeV energies.
