Ridiculously Secret Area

From RWP Wiki

Ridiculously Secret Area 1 (commonly abbreviated to "RSA") is an alleged location in Banjo-Tooie. It unused location text for the Isle o' Hags silos, along with "Silo 8" and "Silo 9." It can be presumed that the area was either dropped or was merely an unused placeholder with a humorous name, although it has caused much speculation over the years as to whether or not such an area really exists within the game's coding.
