1 | Mt. Moon – Found in Poké Ball on B2F. To reach this area you’ll need to take a ladder found near the entrance of the cave. | No |
TM46 Thief is located at the very bottom floor of Mt. Moon (B2F). In order to reach it, you’ll need to climb down a ladder in the middle of the first floor near the cave’s entrance.
But before you’re able to enter Mt. Moon, you must first defeat Brock at the Pewter City Gym and cross through Route 3.
Note: There are no repeatable methods to get more Thief TMs in FireRed/LeafGreen. So the one you get in Mt. Moon is all you’ll have for your playthrough.
TM46 Thief Location (Step-by-Step)
Step 1: Starting at the Pokémon Center next to Mt. Moon, head east to enter the cave.

Step 2: Now inside Mt. Moon, head north from the entrance.

Step 3: Keep going up and curve a bit towards the east, passing the trainer standing next to the wooden sign.

Step 4: Ahead to the north you’ll spot a ladder, but this isn’t the one we want. So go past this and just keep heading east.

Step 5: After passing that ladder, veer up to move around the large rock formations. Then start moving west.

Step 6: Continue following the path west through Mt. Moon, and when you hit a rock wall then turn south.

Step 7: A few paces south will be another ladder – and this is the one we’re looking for.
Climb down the ladder to reach a passageway in B1F.

Step 8: After climbing down, you’ll spot another ladder ahead to the left. Take this ladder down to the lower floor (B2F).

Step 9: Now on the bottom floor of Mt. Moon, you’ll spot TM46 Thief on a raised rock platform ahead.
The battle with the Rocket grunt is optional if you go up the left-hand stairs to reach the elevated rock platform with the TM.

Thief is a Dark-type move that inflicts damage at 40 base Power. But most players aren’t getting this TM just for dealing damage.
Because Thief has a much more valuable effect:
Thief will also steal the target’s held item if they’re holding one.
- If used in a trainer battle, the item is stolen permanently but will regenerate (meaning the same NPC’s Pokémon will be holding the same item in rematches).
- If used against a wild Pokémon, the item will be stolen permanently and added to your Bag.
Because of its poor damage and temporary item theft, Thief is scarcely used in tougher battles.
The move is much more useful against wild Pokémon, because there’s a long list of items that can only be acquired by stealing them from specific Pokémon.
For example, Thief is commonly used to steal Lucky Eggs from wild Chansey. Although in FireRed & LeafGreen you can only find Chansey in the Safari Zone, so Thief is unusable for getting Lucky Eggs in this gen.
But if you want some other ideas then here’s a small list of other useful held items that you can farm by stealing from wild Pokémon:
