Are you hapoy?

Dude if my dad helped me with games when I was little I would've loved him even more than I already do

You get a few k coins just by playing through really. And Mario odyssey is addictive so that would be fun. Rock on dad for helping out your boy.

It doesn't really take that long.

It’s really easy to farm coins at Bowser’s castle though.
Also, if you want all 999 moons, you may have to farm there again.
