Okay well the purple coin levels only show up once you beat the game (as Mario or Luigi) once. Once you get further in the game (if you haven't already unlocked these) you will discover some floating comets called "Prankster comets" which make the galaxy's behave in different ways (you will find out how). Prankster comets come in five different colors, Blue, Yellow, White, Red, and Purple; each different color of prankster comet does something different then the other which you will discover later. The Purple prankster comets can only be unlocked when you beat the game once with Mario or Luigi which then cause (when theres a purple comet over the galaxy) the galaxy's to unlock levels where you collect purple coins.
thanksappreciate it
Your welcome.
I wonder if there will be different comets in SMG2.
hmmm not sure but I can't wait for smg 2
I think they should bring back the penguin suit and make it into a penguin mushroom.
By the way isn't SMG2 coming out next week?
