Right when you enter Mt. Ember which is all the way to the north on One Island, go to the right and you will see two Team Rocket members talking about treasure and the passwords to the warehouse. Fight both of them and once you win they will say not to follow them into the cave if you know what's good for you. Follow them. Go through the cave and move all the boulders in your way until you get to the level where you can go south in the cave two different ways. Go down the first one and you'll go down a ladder into a room filled with a bunch of braille signs. Go down the other ladder in this room and the Ruby will be right in the center of the room. Use an excape rope or go back out of the room, through the braille sign room, then go right to the second way to go down and follow that to the exit of the cave.
Give it to Celio on one island.
give ruby to cello

Talk to celio in 1 islnad and he will ask you to get a ruby. The ruby is in 1 island inside MT.Ember.
After fixing the Network Machine on One Island, you can trade a Mudkip from Pokemon Ruby or Sapphire. You can't catch a Mudkip in Pokemon FireRed.
Im not sure about the ruby on island 1 but I know that there is a sapphire at the bottom of the dotted hole
in firered
you need both ruby and Sapphire to get there. :)
You must give the Ruby to Celio to get the Rainbow Pass, allowing you to get to 4th-7th island.
No.
After you fix the machine on 1 Island with the ruby and sapphire, it allows you to trade with the games emerald, ruby and sapphire. You can trade a Treeko from one of those games to FireRed.
