@Trinket Oh, I'd forgotten about the Shampoo! We never did get the Beautiful Hair in any of our playthroughs.
Have you ever seen the Shadow the Hedgehog 100% that's estimated to take, I think it was a couple years?
@Trinket The reasoning behind that is that the game lets you take several paths out of each level, either "hero", "dark", or "neutral" if we remember right, and you get a "title" for every path you complete--one per playthrough. That means you need to get to the credits somewhere around two or three thousand times, if I remember right, to obtain all the titles.
@Rosemary This reminds me of the Baten Kaitos 100% speedrun that takes two weeks b/c you have to wait for the Shampoo to turn into the Beautiful Hair
