As admitted by Mitsuhiro Takano (the original script writer for Star Fox 64) in an issue of Iwata Asks regarding Star Fox 64 3D, the development team had initially planned on including more aquatic stages based around the Blue Marine in the original game, but these were removed because they felt they dragged down the pace too much. In the Japanese version of the Aquas stage in Star Fox 64, Falco says:


English SF64's equivalent to this is "This thing will never hold together."

Apparently, this was the result of Takano feeling bad about there only being one underwater stage in all of SF64's single-player mode.

Going by files pertaining to Star Fox 64 found within the Nintendo Gigaleak, it seems one of these cut Blue Marine stages was known as カトレア (Katorea), which properly translates into Cattleya. Cattleya is a genus of orchids, which adds more credence that this was planned to be a beautiful water planet. The planet's initials (CL) show up in many other other source files, which gives clue to what it would've been like; for example, fox_edisplay references CL_SHIP0, CL_SHIP1, and fish00, whereas fox_boss.h refers to CL's boss as 鯖/saba, or "mackerel.” fox_jyuza.o meanwhile refers to a "saba snake", which heavily implies that the stage's boss would have been a giant fish creature or an eel of some kind.

Most of the other files label CL as "Colony", which implies that Cattleya would have been home to underwater cities. In beta versions of the map, CL is positioned between where Area 6 and Bolse would be, and presumably would have led into the cut planned Venom Normal route where Fox would have battled Andross on-foot with a bazooka.
