Found within the E3 2002 kiosk version of Star Fox Adventures is an unused cutscene of Fox talking with Tricky, Peppy and Slippy after placing presumably the final SpellStone. Various unused SFA voice clips sync up perfectly with this sequence, revealing the dialogue exchange to be:


This presents bit of a different story from what is presented in the final game. In the retail release, it's discovered that returning all of the SpellStones to the Force Point Temples does not single handily restore Dinosaur Planet to its original state, and that Fox also needs to return all of the Krazoa spirits to Krazoa Palace to fully stabilize the planet, in addition to freeing Krystal from Krazoa Palace.

Here, it does seem returning the SpellStones restores the planet, and collecting the Krazoa spirits is for a separate task, that being merely freeing Krystal.
