That's pretty simple. Work on the dragon's esteem issues.
I mean, you already laid out the to do list:
*Fix Dragon
*Have Rick James take you AND the Ark into the correct movie.
*Use the Ark to kill all of the Nazis, because that's what they do?
**Backup Plan, pack guns in the Ark, just in case the nazis don't just all die.
*Acquire Matt Damon's skull.
*Say "Matt DAAAAMON"
*Okay, get serious.
*Find clues inside the skull?
