aka Invaders of the Lost Gold
How bad is it? It's among the worst Italian horror/adventure films.
Should you see it? No.
Japanese soldiers are attacked by cannibals in the Philippines and the few survivors stash treasure they're transporting. Decades later, a ragtag crew of stereotypes (Stuart Whitman, Woody Strode, Harold Sakata and Laura Gemser) go to recover it. There's huge plot holes - Gemser dies while swimming for no reason, for example - and after the opening scene, there's little explicit violence; people tend to die by their own inept misadventures. There's a rubber crocodile. There's also a plot twist that's quite predictable.
