Star Fox Adventures contains a peculiar character named the WarpStone, a living stone creature that has the ability to warp users to the top of Ice Mountain and also Krazoa Palace, where Fox will need to deposit all of the six Krazoa Spirits he acquired through partaking through the Krazoa's trials in order to save Krystal, who is imprisoned at the top of the Palace. Underneath the WarpStone also lays the Game Well Maze, where Fox can deposit any of the Cheat Tokens he's collected from Scarab Wells hidden in the map throughout his Adventures to unlock extra features and also cryptic messages.

In Dinosaur Planet, the WarpStone was originally meant to be two different characters, the SwapStone twins known as Rocky and Rubble. Hence their name, their original purpose was to let the player be able to switch back and forth between Sabre and Krystal's adventures. Sabre would utilize Rocky in an area called SwapStone Hollow, while Krystal would utilize Rubble in her equivalent, SwapStone Circle (which is also where the LightFoot Village was situated). Both characters would also retain the ability to warp their respective character to Warlock Mountain (the predecessor to SFA's Krazoa Palace) where the characters could similarly deposit the Krazoa spirits they acquired from the Krazoa shrines. Underneath the SwapStones was the only in-game store where Sabre and Krystal could purchase items, maps, etc. Curiously, their bio claims that they were created during the age of the Krazoa, by being mined from the magic rock of Warlock Mountain, and that they assisted in the creation of the Force Point Temples and the Krazoa shrines.

As Krystal's playable co-protagonist role was scrapped in SFA outside of the prologue, the SwapStones were merged into one character, the WarpStone, and SwapStone Hollow was renamed to ThornTail Hollow. SwapStone Circle would be effectively removed, but the LightFoot Village segment was heavily expanded into its own distinct area. In place of being able to swap to Krystal, Fox could be teleported back to the top of Ice Mountain where he could replay the jet bike race against the SharpClaw. While early design documents and leftover data from the E3 2002 kiosk build of SFA indicate that the store was still planned to be located underneath the WarpStone, in the final game it was relocated to the middle of ThornTail Hollow as its own distinct establishment, the ThornTail Store, and the alformentioned Game Well Maze took its original intended spot.

Diving in to the game files, it seems Rare had also intended on letting the WarpStone teleport Fox over to additional areas such as Cape Claw, Moon Mountain Pass, and the Force Point Temples, but this was scrapped and currently, the WarpStone can only warp you to Ice Mountain and Krazoa Palace.
