We study the signal from the pair production of $t$-squarks at the Tevatron under the assumption that their two-body decay to charginos as well as their three-body decay to $W$ bosons is kinematically forbidden. In this case, the stop dominantly decays via $\widetilde{t_1}\rightarrow c\tz_1$, so that the signal consists of two charm jets together with $\eslt$. We reevaluate this signal using ISAJET~7.01, and show that if the stop mass is below about 100 GeV, there should be as many as 50-70 events in the accumulated data sample of the CDF and D0 experiments even if the LSP is as heavy as 50 GeV. We have also studied the possibility of tagging the $c$-jet by its semileptonic $\mu$ decay, but find that the event rates are too small for this to be viable except for values of stop and LSP masses that yield a robust signal via the conventional $\eslt$ search.
