One attempted to deceiveGeneralSkywalker by hiding behind the dead body ofRedeye, but was discovered and had two of its legs sliced off, then was shot repeatedly by clone troopers. The second droid escaped up theturbolift shaft and was dispatched byObi-Wan Kenobi. Both droids, after being destroyed, launched dozens of smallprobe killer droids through pits on their heads. The third droid released the probe killer droids while still hidden, then attackedCaptainRex, but was dispatched after Skywalker cut off its legs with alightsaber throw and Rex had unloaded severalblaster pistol rounds into the pits on its head.
