Stage: Bermuda Triangle This marble-like entity is referred to as "Balbi" and "Varbi" (both valid romanizations of the katakana バルビ) in the data for Sonic Wings Special. It is the final boss if the player chooses the Bermuda Triangle route. Balbi might be based on a crystal sphere allegedly discovered in 1968 by Ray Brown within a pyramid-like structure near the Bahamas. Although the crystal pyramid has been proven a hoax, photos purported to be of the sphere show a clear crystal ball about the size of a tennis ball. It contains fractures which supposedly produce images of pyramids and a human eye within the crystal.
