Terror in the jungle (1968)

IMDB

This epic Bad-Film used to play in the late night/early morning TV slot in the late 70's.  It spends the first half hour introducing various characters boarding a plane including a young blond boy, the star, a group of nuns retuning the body of a sister, and a rock group.  Just as we get to know them the plane crashes in the South American jungle. The boy floats away atop the nun's coffin as everyone else is eaten by alligators. This shock sends us into a fevered dream of the adventures of this lad that include being worshiped by cheesy natives and a stuffed animal that magically becomes a real big cat.
