red: after u get 15 stars go to the middle of the castle, and look up at the cloud painting.
Green: in the portal that looks like metal that u jump down into u do something, I forgot exactly what to do.
Blue: find 2 pillars in the castle and ground pound them. I forgot exactly where they are but somewhere in inside the castle they'll be partly submerged. after u do that go into the "moat" around the castle and there should be a pit, complete that quest and yay!
-EDIT- wow corny's came while I was making mine and makes mine look like a crayon-drawn map
