Something I realized later was that gold is much denser than ducks. So Scrooge could not have dived into his silo of gold without injuries equivalent to diving onto a sidewalk. Ehh, it was still a great visual.
No, no, that's an explicit skill of his. A villain once steals his fortune with the goal of diving in line he does and just bounces off the surface, hurting themself.
People have noted this for some time and I think the comics even gave him a superpower where money can never hurt Scrooge.
