One of Krystal's many areas from Dinosaur Planet that got scrapped in the transition to Star Fox Adventures was Discovery Falls, which consisted of a massive series of waterfalls and hidden caves. This was the first area that Krystal was meant to visit after rescuing Princess Kyte from the SharpClaw within Cape Claw, and was also home to her first Krazoa shrine test, the Test of Combat. Other notable characters encountered here include a member of the HighTop tribe (a race of sauropods), a friendly SharpClaw that teaches Krystal the Foodbag mechanic, and a mysterious mole creature that Krystal must feed in order to to help her dig additional tunnels within one of the caverns. This mole creature, internally referred to as "DFmole" in the game files, has been affectionately named "Capy" (short for "capybara") by some within the Dinosaur Planet community. This area was also where Krystal would eventually acquire an artifact of the Krazoa that would let her access more areas previously barred off in Cape Claw.

As mentioned before, this area would be scrapped entirely in the final Star Fox Adventures game, but some elements of it would live on elsewhere, namely the Test of Combat (which now exists in Moon Mountain Pass, fittingly as Fox's first test) and its background music, which now plays in Cape Claw, and was also remixed in romantic saxophone form as Krystal's theme.
