Originally, going by some of the initial concept art as well as early gameplay footage for Star Fox Adventures, the tip of Krystal's staff was meant to transform whenever Fox performed one of its magic abilities. For example, when Fox performed the Ground Quake ability, it'd transform into a hammer. Curiously, one of the pieces of concept art mentions the staff transforming into a wing tip to give Fox the ability to glide, which goes unused in the final game. The models for these staff transformations were also found within the E3 2002 kiosk version of Star Fox Adventures. Ultimately, this went unused in the final game.
