Did you know that before you partake in a Krazoa Spirit's test, if you stand around them long enough, they will utter/mumble/whisper Andross's name? Yes, even as early as the one when you play as Krystal. In fact, when Krystal says "It's you!" in Dinosaur Language after releasing the first Krazoa Spirit, it has a weird transliteration where she's actually verbally saying "Andross!". Because of all these many pertaining factors, I knew Andross was back in town for some more crime scene. As I kept doing the Krazoa Shrine tests, I also realized that the Krazoa Spirits were designed to be some kind of brain cell and/or brain neuron, as well as some kind of skull effigy. I also felt that when you first come across that tall Krazoa guy with the first spell stone at Moon Pass, the body resembled the tubes that Fox had to fly in/through in Venom of Star Fox 64, and that the body of the Krazoa guy was symbolic to that too in some kind of nostalgic honorary regard. Then of course if you played along with those Cheat Tokens, it also alludes towards Andross too.
All in all, I really love Star Fox Adventures. I played the heck out of the game. I beat it weekly in my teen years, and I've been beating it annually in my adult years every July. This game is my comfort food, and I am in bliss with it. Even though I am aware of circumstances, I will always still say that... I hope one day the game will get a HD Remake port over to whatever future Nintendo console, where they will include everything that was cut out of the game because of how the game was rushed out. I also hope I will get another Star Fox Adventure game. I think it's such a lovely touch to the Star Fox series.
With that said, I also hope that Krystal will get her own stand alone games though... with a much better character design, mind you, and her very own fleshed out story telling/character narrative. It truly sucks what happened to her fate because of Miyamoto.
