Titre original : Operation: C.A.N.Y.O.N.
The scene opens up with a large barricade in the surrounding desert that's blocking a large amount of traffic. 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. It is then discovered that the Kids Next Door are blocking all ground and air access towards the Grand Canyon, with Numbuh 2 forcing planes to turn around from passing over the area.
