Find: 1 Elixir, Added Effect Materia, Black M-Phone, 1 X-Potion, Fairy Ring, 1 Turbo Ether, & Gravity Materia.

Drive west to the shallows and cross the river. Drive north until you can enter the canyon area. Drive north and wind your way through to Cosmo Canyon. The city built into the Cliffside is what you are looking for. If you drive past Cosmo Canyon, your car will break down!

Talk to the man at the gate to get in. Talk to Red XIII (he's on the stairs), and your party will split up. If you talk to the construction-worker type guy walking around near the large flame, he'll tell you about Planet Life studies. When you talk to him and your car is broken, just say the second option - "no" - and he offers to fix it. Now head into the Arms Shop and read the paper posted there, it's the Turtle’s Paradise Flyer #4. Buy some weapons and save. Go up the stairs and to the back room to hear the story of AVALANCHE. Work your way up to the next floor, and explore some more. There is a Materia store here. Climb the ladder to hear Bugenhagen's story.

Go talk to one of your friends to form a party. Barret is in that back room behind the weapons shop; Aeris and Tifa are at the Inn. Go back to the observatory and Bugenhagen explains about the Lifestream. Walk back down to the town, sit by the Cosmo Candle and talk to everyone. After you talk to Red XIII, form a party and get ready for a tough, long fight. Sleep at the Inn (BTW, there is an Elixir behind the couch at the Inn), read the flyer outside the Inn door (next to the counter) - it's the Turtle’s Paradise Flyer No. 5, save, and then meet Bugenhagen at the sealed door just under his observatory.

Equip everyone with Star Pendants (protect against [Poison]). Have him open the door, and go in. Climb down the ropes to the bottom. Go right, into the large room. Walk along into the caves and break open the rocks inside when asked. One of them opens a doorway; the others get you into fights. The rock in the third cave opens the door. You should break all four rocks, to learn the Enemy Skill Death Sentence from the Gi Spectors. Go north through the door and into the next room.

Go up and left when the path turns. Walk carefully around the bottom of the oil slick and go down and to the next room to get an Added Effect Materia. Go back and carefully walk back around the oil again. Go up, then left and down the stairs. Go down to get the Black M-Phone. Go north again to get an Ether. Go around and back up the stairs and follow the path up.

Go north again and take the fourth hole from the left. Touch the web and fight the large Stinger. Go up and get the X-Potion. Go back to the part with the five holes and go through the second hole. Touch the web and fight another Stinger. Follow the path left and down into the cave. Hold while walking through the cave to go through a hidden tunnel. Get the Fairy Ring from the chest. Equip it (protects against [Poison/Darkness]). Go back up to where you fought the Stinger, and take the path on the right. Fight the third and final Stinger. Walk through the left wall for a Turbo Ether, and heal up for the boss. Then go up through the cave and fight.
