Volcano Valley Zone is the fifth level of Sonic 3D: Flickies' Island for the Sega Mega Drive and Sega Saturn, coming after Diamond Dust and before Gene Gadget Zone. As with other stages in this game, Volcano Valley consists of two standard Acts followed by a third Act containing only the boss fight. In Acts 1 and 2, Sonic must free captured Flickies from inside badniks, depositing five of the birds into a Goal Ring to progress between sections of the level (usually three per Act).
If Diamond Dust = cold, Volcano Valley = hot. Molten lava pulses through the zone like scorching blood, and the fat man's flamethrower cannons don't help lower the temperature much. Semi-solidified magma, still glowing a dull crimson, coats the craggy bluffs on the interior of this volcano, with giant quartz crystals and petrified remnants of trees jutting crudely out the blistering rocks. The heat is such that a heat haze is visible in the Saturn version of the level, and Robotnik's made the place even less hospitable by throwing in spiked orbs and robotic terrors to boot.
Keep your eyes peeled for the square slabs of beige-brown rock that litter the floor. Hidden beneath a formation of these you can almost invariably find secret passageways down solidified lava tubes, leading to power-up TVs like the very, very, very useful Fire Shield.
This is the last zone in the game to feature Tails and Knuckles, thus it's the last zone where you can get Chaos Emeralds.
Geographically, the Zone is located on the volcano of Flickies' Island.
