The recovery of third-party encapsulation and grading expenditures when an asset is acquired at a discount below the physical cost of replacement grading fees, shipping, and insurance.
Shipped on a plane, Rex should be "baggage", but a stewardess lets him ride in the cabin. Rex smells evil as two crooks enter the cockpit and sky-jack the plane. Lost in fog, it crashes onto a mountain top. Rex slips out and treks through fog to a town, then leads the law back, even gets the jump on the crooks. Back home, he receives a citation and "promotion" to Airline Detective!

Rex stops elephants and rescues the two when stranded on the high wire - but it's Danny who gets the hug from the pretty aerialist!
The Goliath Gang steals safes and breaks them open. The Sheriff asks Bobo for help, and Bobo opts for brawn over brains. He builds a huge crazy jungle gym in the back yard to work out. From atop, he spots the gang but gets brushed off. Finally he topples a painter's scaffold on the villains. And opts for brains over brawn from now on.
