White Cave is the fourth Babylon story racecourse in Sonic Riders. Although not quite the mycologist's wonderland of Grand Kingdom's Shrouded Forest, White Cave still deserves its name for the drifts of colourless fungal spores that rain down on the level throughout the race. Green Cave's mighty trees have been rendered brittle and fragile by the onslaught of pervasive spore-dust, and the giant millipedes have changed from rust-brown to a dull, lichen grey.
With Storm still away engaged on counter-Robotnik espionage in Ice Factory, Jet is relaxing in Green Cave while Wave frets over the albatross' delay. Spotting Sonic practicing on his Extreme Gear, Jet sneaks off from a lecture about leadership responsibility to throw taunts at the hedgehog, before his own EX World Grand Prix race against the E-10000Gs.
