the first one is the ruby go to mt.ember when you get in take a right team rocket will be there after you beat them and they run away go inside the cave then go through it (you will need strength and rock smash to get rock smash talk to the people in the hot spring) for the next one is in the doted hole the door can be broke by using cut after you get through there go to 5 island go to the rocket warehouse then get through there beat the guy who stole the gem and that's how you do it(before you try to get the 2th gem get through ice fall cave on 4 island)
I will do my best to explain it. When Celio says he needs the gemstones you need to get out of the Poke Center and walk towards the EAST and surf to the NORTH. Keep going on Kindle Road battling all trainers and over-coming obstacles. You will need a Pokemon that knows STRENGTH and ROCK SMASH. Go to the hot springs (its a cave north of Kindle Road) and heal your Pokemon. Get out and go NORTH once more, surf and you will arrive in Mount Ember. A bit to the right you will see that Team Rocket has punched a hole through the wall of the cave. In their conversation you manage to capture the first PASSWORD to their hideout: "GOLDEEN need log."
Battle both Rockets and the cave is yours to explore! You will find Ruby inside.
Take it to Celio and he will tell you he needs another gemstone to get his machine to work. Go to Four Island. Get into the Poke Center and Gary will be there to brag once more about how if he is not able to complete his PokeDex, that there is no way you can complete yours. So untrue, but anyway.
Get out of the Poke Center and go toward the back of Lorelei's home, and enter the Icefall Cave. Retrieve HM Waterfall and go up the Waterfall. You will find Lorelei battling Team Rocket there, help her.
--I am completing this stage on my Leaf Green as I type--
Lorelei will demand the Rocket to tell her where the Pokemon they've caught are. He will say that the Pokemon are in the Rocket Warehouse on Five Island. He also says is near impossible to enter it as you need TWO passwords. You already know one, you need to go and find the other. So if you head to Island Five you will be wasting your time. The second password can be found on SIX ISLAND.
Go to Six Island and walk EAST of the Pokemon Center and go through a long maze to find what is known as the Dotted Hole. Use the move CUT on the door to get in. Go down the hole and you will find yourself in a 4 hole puzzle!
To solve it, go through the holes in this order:
UP-LEFT-RIGHT-DOWN
The Sapphire is there, but... someone keeps you from getting it!
The nerd who snatches your Sapphire will tell you the password to the Team Rocket hideout on Island Five. Which is "Yes, nah, CHANSEY."
Finally, you must go to Five Island to retrieve the Sapphire in the Team Rocket's hideout. To get there you must stay on the sandy area once you get out of the ferry boat and go toward the right. Keep going and battle 3 rockets.
When you get to the door you will be able to enter with your two passwords. To be able to get the Sapphire you need to go through the conveyor belt puzzle and battle everyone. It is not too easy but once you have battle everyone you will get your Sapphire.
Take it to Island One and give it to Celio.
In Pokémon LeafGreen you need to give a gemstone to Cielo to continue. You can find this gem in the Volcano north of town.
the ruby on 1 island and Sapphire on 2,3,or 4 island
the Sapphire and ruby plates in leaf green are two plates that you have to give to celio to be able to find one of the three legendary dogs.
you don´t. youd have needed to go to a certain poketour. now you can only get one through cheating
impossible
The green part of the leaf is green because of the chlorophyll inside
you can, the person with the fire red or leaf green needs to win the game then get the ruby and sapphire and give them to the professor that is building the machine to trade with ruby and sapphire games on island one
You get the Sapphire in ruin valley and give it to celio.
give it to celio and then mewtwos cave will be unlocked
Get past every island and then you will get the gem from a little girl on island three.Take the gem to a guy named Celio on island one.
Celio was introduced in Fire Red and Leaf Green, the Generation I remakes that included parts from Generations II and III. In other words, he is not present in the original Red, Blue, or Yellow.
Nothing to do in Ruby. Just find a ruby and a sapphire in leafgreen or firered and give them to Celio.
You can only get the dogs if you beat the game and have the national dex im not completely sure if you have to deliver the ruby and sapphire to celio to get them try to do that and if you can't then give the ruby and sapphire to celio.
beat the elite four, get the national pokedex, talk to celio on one island, get the ruby in mount ember where the two rocket grunts were, give the ruby to celio and he will give you the pass.
this is not a trick question it just needs thought a dark green leaf would have more chlorophyll because chlorophyll is the substance that causes the leaf to turn green
he is over in the Pokemon center on one island in front of the machine that links to Ruby and Saphire from Fire Red/ Leaf Green
the Sapphire and ruby plates in leaf green are two plates that you have to give to celio to be able to find one of the three legendary dogs.
In Leaf Green And Fire Red, for Johto Pokemon you need the national pokedex; this was obtained when you gave the blue and red gems to Celio in Island 1
I wreckon Mewtwo is the best Pokemon to get Leaf Green. You can get after you bring the ruby and sapphire to Celio on Island 1. It is Lv 70 and it is in Cerulean Cave. I got a Mewtwo with around 326 special attack. Mewtwo also has the best recovery move in the game.
