Has anyone else had this problem in Sonic Unleashed for Wii?

Ok, so you know the moon and sun metals. I need 69 moon metals to open up any new doors in the temples, but I've beaten every mission and level I've unlocked. S rankings on all the day stages, and I checked through all the villages during the night and day. I've also completely cleaned out all the temple areas I can access. Am I missing something somewhere, or are there missions hidden in the levels somewhere? I donno. Help please!
