Over here we see that Scrooge has a pretty unique skill that he can swim through money.
In the entire Duckverse (Ducktales, Barks, etc.), do we ever see anyone else with this skill?
In the new Ducktales, Season 1, Episode 23 "The Shadow War" shows the characters swimming in the money bin with varying degrees of success.
Huey, Dewey and Webby swam on top of it, Donald Duck hurt his butt on the surface trying to do a cannon ball, Launchpad got stuck head first and the rest were just sitting/walking on top of it all.
A clip is available here.
