This is likely the most asked question on these boards... but I think I MAY be able to help.
Anyway, the 6 most commonly missed goals are Forest Ghost House to Forest of Illusion 1, and the 5 NORMAL Star world goals. (I.e, Star world 1- Star Road 1, SW2-SR2, etc.).
Try those. If you STILL don't have the 96th goal... tell me, ok?
