Tips:
- To obtain the Yellow Trinity ability, you must complete the Hercules Cup at the Coliseum.
- There is a Red Trinity mark at Oogie's Manor. It is temporary, so if you miss it and finish the area, defeating Oogie, then it is gone for good. This is the only Trinity mark that is temporary. Don't miss it!
