One of the most notable cuts in terms of characters going from Dinosaur Planet to Star Fox Adventures was the character of Randorn the Wizard.

Randorn, along with his two children Sabre and Krystal (biological and adopted respectively), all came from a planet named Animus that comprised of two warring tribes: the Wolvens (that Randorn and Sabre belonged to) and the Vixons (which Krystal belonged to). As the leader of the Wolvens, Randorn had another older son (thus Sabre's older brother) that he sent into battle against the Vixons, only for him to end up killed. Overwhelmed with grief and guilt, Randorn abandoned his tribe and Sabre, and proceeded to go on a murderous rampage, destroying any and all Vixon tribes he came across with his magic.

That was, until he came across an orphaned six year Vixon child. Realizing the monster he became, and also feeling guilt about killing her parents, he adopted the child and named her Krystal, raising her as his own daughter. After several years of exploring the woods together, Randorn and Krystal would eventually come across a hidden temple with a technological device known as the "communication chamber", and from there they received an SOS from the King EarthWalker from a world known as Dinosaur Planet, asking for their help against General Scales and the SharpClaw who have begun to take over the planet. Wishing to atone for his past transgressions, Randorn ordered Krystal to find his son Sabre and then jumped into the swirling vortex that teleported him to Dinosaur Planet, where he battled General Scales only to get mortally wounded, now only barely being kept alive by the magical energies of Warlock Mountain. He leaves Sabre and Krystal behind a message, saying that they must come to Dinosaur Planet and rescue Prince Tricky of the EarthWalkers and Princess Kyte of the CloudRunners from the SharpClaw, who plan on making their respective tribes fight and blame each other.

For the rest of the game, he would reside at Warlock Mountain, and the player would visit him every time they had to return with a Krazoa spirit, sometimes giving advice and also magic energy in case the player is running out. According to the leaked condensed story, the player would eventually have to make a choice to save the dying Randorn by planting MoonSeeds in special locations. If they do, he'd be brought back to health and have a "special surprise" for Sabre and Krystal. There doesn't seem to be any sign of this feature in the leaked December 2000 build of Dinosaur Planet, possibly indicating that this was scrapped.

The aformentioned December 2000 Dinosaur Planet build, which already was beginning to incorporate Fox McCloud as a replacement for Sabre into the game, suggests that Rare actually at least experimented with keeping Randorn in the game even with the new focus on Star Fox, down to creating new voice overs and rewriting the dialogue to suggest that Randorn was previously friends with the McClouds, even expressing guilt over not going along with the original Star Fox team to their investigation of Venom that led to James' death at the hands of Andross and Pigma (Randorn even directly mentions the latter, claiming that he suspected he was a traitor all along).

Unfortunately, Randorn would end up being removed entirely in the final Star Fox Adventures game.

Dinosaur Planet was originally meant to have eight collectible Krazoa spirits, four for Sabre and four for Krystal, and each of these spirits would be obtained by each character finding various Krazoa shrines found throughout their respective maps, each containing a challenge or trial testing their abilities or even character. Sabre would partake in the Tests of Strength, Skill, Magic and Sacrifice while Krystal would partake in the Tests of Combat, Character, Fear and Knowledge.

In the final Star Fox Adventures game, this was cut down to only six Krazoa spirits and shrines for Fox to find, with only five of them even being proper tests, those being the Tests of Skill (renamed to Observation), Combat, Fear, Strength and Knowledge. The final "test" is a rather anti-climatic "boss fight" with General Scales, which is interrupted by Andross forcing Scales to hand over the last Krazoa spirit. Unused voice clips and also hints found within the 2002 E3 SFA kiosk, as well as comments from SFA developers on Rare's scribes, indicate that the dev team planned on General Scales having a true boss fight: essentially a rematch against his flying galleon like in the game's prologue, though instead of playing as Krystal flying on the CloudRunner, it'd likely would have been Fox in his Arwing.

As such, looking at internal files for SFA (as well as its E3 2002 kiosk), Rare had also intended on there being one final true test: the Test of Sacrifice, which fittingly enough was Sabre's final test in Dinosaur Planet and its overall final spirit in general. In both versions of the game, it would have involved Sabre or Fox having to "sacrifice" themselves in order to save an apparition of Tricky. Unused hint texts found within the E3 2002 kiosk heavily imply that Fox would have partaken in the Test of Sacrifice right where the General Scales encounter is today, before he freed Krystal from her prison at the top of Krazoa Palace and also before fighting Andross, who he unknowingly resurrected by releasing all of the Krazoa spirits. The music track that was (as revealed by the leak Dinosaur Planet N64 ROM) intended for the Test of Sacrifice even appears as an unused track found within SFA's sound test, and there's also unused voice clips of Tricky begging Fox for help that very likely pertain to this test. Both of these indicates that this was a very late cut.

Internally, the General Scales "boss fight" shrine is referred to as "nwshrine", which adds up considering that the Test of Sacrifice was meant to be found by Sabre at the Northern Wastes (now now as SnowHorn Wastes) in Dinosaur Planet.

While merely referred to as the King EarthWalker in the final Star Fox Adventures, voice clips from Dinosaur Planet on the Nintendo 64 indicate that he was intended to have a name: "Albada". Both the Queen EarthWalker and Sabre have voice clips that refer to him as such.

Star Fox Adventures primarily takes place on a planet filled with dinosaurs known simply as "Dinosaur Planet". It would return or be referenced in future games like Star Fox Assault and Star Fox Command, as well as "Star Fox Zero - The Battle Begins", a promotional anime released to commemorate the release of Star Fox Zero, but it would instead be referred to with a different name: "Sauria".

It turns out Rare had always intended Dinosaur Planet's real name to be Sauria, as leaked voice clips from the implied climax of the original Nintendo 64 Dinosaur Planet feature the Krazoa name dropping it as they begin the alignment of the "Majestic Eight" planets to wreak havoc on the universe using the power of their god, the Quan Ata Lachu. An edition of "Ask Uncle Tusk" on Rare's old website revealed Dinosaur Planet's name to be Sauria as well.

Star Fox Adventures began development as Dinosaur Planet, which originally began development as a direct sequel to Diddy Kong Racing, starring Timber the Tiger (who himself was intended as the main character of DKR when it was Pro-Am 64, before Donkey Kong characters were incorporated into it). It was pitched as an adventure/racing hybrid where Timber, equipped with a rucksack, little fingerless gloves, and a baseball cap would go back in time and team up with a younger version of Tricky, a boss from the first DKR. Wizpig, the main antagonist and final boss of the first Diddy Kong Racing, was also involved. It would seem a working title for this iteration of the game was "Dino Island", going by several posts on former Rare employee Ed Bryan's Twitter account.

Eventually it was decided to rework the concept into an entirely new original IP with no story connections to DKR and two new main characters, named Sabre and Krystal, and also make it a full-on action-adventure game directly inspired by The Legend of Zelda: Ocarina of Time. DP/SFA's various racing segments are said to be remnants of the original DKR successor concept, and while he retained the name of the DKR boss (something Rare seems to regret), Tricky would wind up becoming his own distinct character. Several files within DP/SFA's data also mention Timber, obviously a remnant from when he was the star.

Sabre and Krystal were in turn eventually replaced by Fox McCloud as the main playable character when the game was rebranded into what we know today as Star Fox Adventures, though Tricky would remain as his sidekick and Krystal would remain as a main character.

Many fans today recognize Star Fox Adventure's Shopkeeper's name as "Shabunga". However, the game's development team never intended the Shopkeeper character to have a name, even as far back when it was still Dinosaur Planet.

"Shabunga" was initially the name of a cut NPC character from Dinosaur Planet, a mutant creature that Sabre/Fox and Tricky would come across in an area known as Willow Grove, the bridge between SwapStone Hollow (ThornTail Hollow in SFA) and Dragon Rock, which was becoming a strange and mutated land as a result of General Scales' and Drakor's actions within the latter area, which was also mutating its inhabitants. As such, Shabunga, and supposedly other mutants according to the Dinosaur Planet condensed story (though none appear in the leaked December 2000 build) were cast off and sealed away within Willow Grove by the ThornTails that lived in SwapStone Hollow, frightened by their now warped appearances.

This mutant character was said to be an alchemist and also one of the SpellStone guardians, and thus was required to revitalize General Scales' Kamerian Belt (or "Krazoa Star" as Shabunga puts it), to allow Sabre and Tricky to enter the mutated wasteland Dragon Rock unharmed, and would later be required activate the SpellStone acquired from defeating Dragon Rock's boss, the Kamerian Heart.

With Willow Grove removed in the final game, Shabunga would appear in SFA as an enemy type known as the "FireCrawler" that appears in Moon Mountain Pass and also all over Dragon Rock. His role as the SpellStone GateKeeper of Dragon Rock would then be given to a generic quiet ThornTail that resides in ThornTail Hollow.

Curiously, SFA's Nintendo Power guidebook and also official English website would both re-appropriate the mutant's name to the Shopkeeper, claiming his name to be "Shabunga", despite the actual game just merely referring to him as the Shopkeeper. It turns out there's a reason for this: looking at the Japanese localization for Star Fox Adventures, it appears that NCL did indeed repurpose the "Shabunga" name behind Rare's back for the Shopkeeper as he's called that both in-game and also all over its ancillary material. For example, in the Japanese version of SFA, the ThornTail Store is renamed to シャブンガの店 (Shabunga no mise), which translates to Shabunga's Shop in English.

Another notable example is when Fox is talking to the Blue SnowHorn in SnowHorn Wastes; in the English version, the latter has this to say:


Retranslating the Japanese subtitles in the Japanese version of the game, however, reveals:


It would seem that whoever wrote the Nintendo Power SFA guide was given the memo about this.

Star Fox Adventures was at one point called "Star Fox Adventures: Dinosaur Planet". This name referenced both original incarnations of the game, Rare's "Dinosaur Planet" and also Nintendo EAD's "Star Fox Adventures" that was in development around the same time; both ended up being merged into the same project, hence the original title, though sometime before release, the "Dinosaur Planet" subtitle was dropped, leaving the final game named as just Star Fox Adventures.

Curiously, when looking at Star Fox Adventures save data on a GCN memory card through the Wii, it actually includes its original "Dinosaur Planet" subtitle, as well as using the Star Fox emblem present in the beta logo for the save data icon. This was not the case in the GameCube's data card management menu.

Star Fox Adventures was originally a game called "Dinosaur Planet" and was unrelated to the Star Fox series. The game featured Krystal as the main protagonist and was to be for the Nintendo 64.

When Shigeru Miyamoto noticed the similarities of the characters to Star Fox, he asked Rare if they could change it, resulting in Star Fox Adventures.
