Best place to farm star bits in SMG2?

I have 241 stars currently, just need 9999 star bits so that I can unlock the comet in the grandmaster galaxy. Where is the best place to get star bits? I have been going to the melty monster galaxy and doing the 'rolling down memory lane' star over and over and it works alright, but I was wondering if there was a faster way? Personally I think it is a pretty gay time sink to require 9999 star bits to unlock a comet. It isnt fun just going and collecting them all.

I think that rolling lane in Melty Monsters is the fastest way to get star bits, maybe you can try Sweet Mystery or Twisty Trials

If you just collected them while you were playing through the game this wouldn't be a problem. They really give you plenty of time to collect them casually if you just pick up like 50 per level...

Anyway you're playing probably the best level for star bits so just keep doing it.

I started off with about 5000 star bits at that point. I farmed the rest at the Rolling Lane star in Melty Monster Galaxy. It took about half an hour.

I have about 3000 after getting all the green stars, need the other 6999 to get to 9999. I didnt avoid star bits while playing, I just didnt go out of my way to collect them.

A probably-more-fun way would just to be to start another file and play thorugh some of the game again and deposit the star bits you collect to the banktoad.
