There is no set amount of Shine Sprites required to get to Corona Mountain. To get to Corona Mountain, you have to defeat Shadow Mario(Bowser Jr.) in each world. This is usually the 6th or 7th Shine Sprite on the list. At minimum, I would say that it takes 55.
you need to complete the game. if not, collect 80 shine sprites
between 30 or 40
80 shine sprites and if you beat the game you get a shirt from that glasses giving guy
I believe you need either 35 or 45. one of the two.
nothing you just need to complete all seven stages on part seven
It depends on how mane shine sprites you collected maybe over 70 shines you will get there
You must complete every Episode 7 in every stage. That is basically, All the Shadow Mario Stages.
Get like 70 shines.
89
in super Mario sunshine
120
You have to finish level 1-7 in each world. The entrance is behind the shine gate... I think.
you need to complete the game. if not, collect 80 shine sprites
If you really wanted to know, why would you ask on wikianswers? Just use IGN. http://guides.ign.com/guides/16713/index.html
between 30 or 40
The only thing similar is that it is 3D and you collect things in super Mario sunshine you collect shine sprites but in super Mario galaxy you collect stars so it's kind of similar
complete all the levels and find the ??? ones
