Forums  /  Phineas and Ferb: Ride Again  /  100% category?

What would be the conditions for a 100% category in this game? Potential requirements:
¤All custom parts collected and added
¤All repairs
¤Some requirement regarding the Candace minigames
¤Out-of-bounds glitch is banned completely

Which of these should be added? And are there any that I'm missing?
