Mt. Moon is a three-level cave in the middle of Route 4. Team Rocket can be found next to a sign directly north of the entrance. They’ll tell you about a rare fossil hidden somewhere in the cave.

Investigate each area to battle all Trainers and pick up all items. The first ladder will lead down to a long tunnel. Follow this path to another ladder, which leads to a small room on B2F. A member of Team Rocket will be standing in the middle of this small room.

Directly to the right of the ladder is a crater with a hidden Moon Stone, and north of that item is a Nugget on a hill.
Return to the ground floor and follow the path to the west. Another Trainer isn’t far away.

North of the last Trainer is a Pearl, and at the northwest corner of Mt. Moon is a man who will give you free Poke Balls if you “run low.” If you have 0-9 Poke Balls in your bag, this man will give you 10 Poke Balls for free. It’s best to use this spot to learn how to catch Pokemon, build a catch combo, and even level up your team through capturing!
When you’re ready to continue, take this third ladder down two levels to B2F. Directly to the north of the ladder is a Revive. Follow the path to the southeast to find another Rocket.

Defeat Miguel to receive P400. He’ll then allow you to choose a Fossil. Choose wisely, as you will only get one! The Dome Fossil revives a Kabuto. The Helix Fossil revives a Omanyte. Whichever fossil you receive, the opposite will be found later in the game once a day.
The path out of Mt. Moon is located up ahead; however, before you can reach the ladder you must battle once more. This battle with Team Rocket will be a double battle, meaning some attacks can affect your partner, one of the opponents, both of the opponents, or everyone on the field!
