KND personnel who is led by Numbuh 5 guard this barricade as a bus full of senior citizens charges through, crashing through the barricade only to be stopped a moment later by a large net trap. Numbuh 5 deters the bus to retreat, falsely claiming that "denture-eating bears" were seen around the area, which causes the senior citizens to hurriedly retreat.
