It's nice to see the Golden Greenies aren't just their to get lots money if you're fast enough there their because they have a job to do and they put life in there behave like the other ghost I mean not literally because there dead but you what I mean. I like for example for jobs: In the secret mines we can see golden Greeny caring a gem thingy that makes ghost stronger and when the Golden Greeny distracting Luigi will the Sninker ambush'es Luigi they even high five! And the example for life we can see Golden Greenies playing in water one playing with it's normal counterpart in the Gloomy Manor and one playing buy it's self in Haunted Towers.
@mariobroultimate1808 They do the same thing with the strong sneakers. Sometimes don't have 50 or a 100 hp. I just don't get it. And I think them having 10 HP is annoying because it's really hard to get a bunch of cash from them.
I went on the Mario wiki, guess what? Only the european french version came up with something we can call creative ("Paktoll", a deformation of "pactole" that means gold mine)
