The purple comet is when you have to collect 100 coins in a 2 or 3 minutes. 100 PURPLE COINS!!!! Wow!
I think its like a remix of Super Mario Galaxy's Purple Comet Missions.
up the comets....
the purple comet can be found in many galaxies,it can be unlocked only if you defeated Bowswr at least once and if there is no purple left to see,ask the purple luma at the left of the starting place to move it
use a comet
cuz i diii
you have to get every star, green star, prankster comet and comet medal
in the first super Mario galaxy you need to get close to finishing the game or just beat that area ( Terrace, Fountain, etc.) Lets take the Good Egg Galaxy for example, u have got to get all the stars available so far in that galaxy, later you will get an alert saying that a comet has just appeared there in the second Super Mario galaxy you simply need a comet medal. They are scattered in the worlds. There is one in most levels, other levels don't have any comet medals. If you get a comet medal in Yoshi Star galaxy you will get a prankster comet there later.
They show up around certain galaxies when you get enough Comet Medals.
You can't. but you can unlock Rosalina that close enough To the SM1
enter the gateway galaxy after unlocking the garden dome then go to where you got the ability to spin a red luma will tell you to get 100 purple coins get 100 purple coins to unlock the red star on the comet observitory
120 Green Stars 120 Power Stars 49 Comet Medals Got the game yesterday. Its awesome and EPIC! (Get all these for the Grandmaster Galaxy) source from : Super Mario Galaxy 2 Game Guide by PRIMA Games and Nintendo
Pressing the + button on the Wii-Remote will pause the game, and will let you un-pause or return to the Comet Observatory.
