Found within the files of the E3 2002 kiosk of Star Fox Adventures is a file called STORYBOARD.bin which reveals a set of storyboard images pertaining to a cut subplot in Dinosaur Planet's CloudRunner Fortress that would have dealt with Princess Kyte's traitorous uncle.

It seemed for two centuries, Kyte's uncle had been cast out by his tribe and now was seeking vengeance by allying himself with General Scales and the SharpClaw. It appears that Krystal and Kyte would combat and defeat this evil uncle, resulting in General Scales betraying him, and in retaliation, Kyte's uncle would attempt to perform a kamikaze attack on Scales and thus sacrifice himself.

While the storyboards otherwise are mostly similar to what is presented in the Dinosaur Planet condensed story and also leaked December 2000 build, there are some notable differences, just to name a few: as Krystal and Kyte enter CloudRunner Fortress, they witness a CloudRunner soldier get killed by one of the SharpClaw's spaceships (presumably provided to them by Drakor). The imprisoned SpellStone guardian, presented as a pachycephalosaurid type dinosaur from the BoneHead tribe in the leaked Dinosaur Planet build (who also appears in Star Fox Adventures with the name "Gradabug") is illustrated as more of a strange stegosaurid type of dinosaur here.

It's rather apparent that these storyboards were meant to pertain to a subarea within CloudRunner Fortress that had already been scrapped by the time of the condensed Dinosaur Planet story and also leaked build: the Trap Rooms, which would of featured an extra set of puzzles and challenges Krystal had to solve before acquiring the area's SpellStone. The storyboards show that the Trap Rooms were to be accessed through the underwater passage in the Fortress' main courtyard, which in the leaked build, instead leads to the jetbike race (in the final Star Fox Adventures, Fox accesses it through the CloudRunner's treasure rooms. Funny enough, Adventures' CloudRunner Fortress also has a scrapped area found beyond the Fortress' flooded courtyard pathway). It is worth pointing out that the March 1999 level list includes "CloudRunner - Treasure", "Dungeon", and "TrapRooms", but doesn't feature "CloudRunner - Race", which makes it all the more apparent the latter replaced the Trap Rooms in the December 2000 build, which would then carry over into Star Fox Adventures.
