|TM36 Sludge Bomb
|Sevii Islands (Five Island) – Team Rocket Warehouse Headquarters, on a table in the top-middle room
TM36 Sludge Bomb can be found in the northern room of the Team Rocket Warehouse HQ. The warehouse building is located on Five Island in the Sevii Islands, and you’ll need to solve an arrow tile puzzle to reach the TM’s exact location.
But to reach Five Island you’ll need to use the Rainbow Pass at the Vermilion City port.
You’ll obtain the Rainbow Pass after defeating the Elite Four and showing Professor Oak your Pokédex with at least 60 Pokémon caught.
TM36 Sludge Bomb Location (Step-by-Step)
Step 1: Starting from the Five Island Pokémon Center, head south onto the beach below.
Step 2: Now on the beach, head east across the sand to cross the island going towards the right.
Then climb the stairs to the north located just beside a small building.
Step 3: Continue northeast across the island, walking through the tall grass.
Step 4: Walk past the Team Rocket grunt ahead, and then veer towards the south to keep following this path.
Step 5: Keep south across the island and take the small set of stairs ahead (also near a Rocket NPC).
Step 6: Continue south from the bottom of the stairs, walking through the tall grass.
Step 7: Across to the west is another set of stairs.
So follow the path over towards the west and climb up the stairs to continue forward.
Step 8: Just ahead is the Team Rocket Warehouse – enter the building once you find it.
Step 9: From the entrance of the warehouse, turn left and you’ll find an arrow puzzle.
Here’s exactly how to solve the puzzle to reach the Sludge Bomb TM:
First take the arrow tiles at the top (these will bring you over to the left).
Step 10: The arrow tiles will lead you to a yellow buffer tile.
Ahead of this buffer tile are two strips of arrow tiles leading north. Take the strip of tiles on the right and travel up.
Step 11: Let the arrow tiles carry you north into the room ahead.
Step 12: From this room you’ll want to head up & around the crates towards the room’s exit on the other side.
Step 13: Just ahead of the room’s exit should be two arrow tile strips leading south.
Take the arrow tiles on your left.
Step 14: These arrow tiles will lead you to another yellow buffer tile.
From here, head north inbetween the arrow tiles.
Step 15: You’ll spot a Team Rocket grunt ahead to the north.
Get past him and then step onto the arrow tiles leading west, which are directly to the left of the Rocket grunt.
Step 16: After letting the arrow tiles carry you across the room, you’ll land on another yellow buffer tile.
Once you’re here, you’ll want to backtrack towards the left a bit & then head north a bit. Make sure to avoid all arrow tiles on your way.
Step 17: Continue northeast across the room, passing between the arrow tiles & only stepping on the regular flooring.
The Sludge Bomb TM is in a room in the center of this area, and you can only reach it by avoiding the arrow tiles here.
Step 18: Continue north into the room ahead. You should see a small table with a Poké Ball item that you can grab.
Step 19: Pick up the item in this room to get TM36 Sludge Bomb.
TM36 Sludge Bomb Details + Uses
|Sludge Bomb Move Details
Sludge Bomb is arguably the best Poison-type move in FireRed & LeafGreen.
Not only does the attack have perfect Accuracy, but it also dishes out damage with 90 base Power.
Sludge Bomb also has a 30% chance of poisoning its target, which is a great bonus.
Too bad there’s only one copy of this TM!
Only Grimer and Muk can learn Sludge Bomb via level-up in FireRed & LeafGreen. So grabbing TM36 can come in handy for sure.
Even though it’s a late-game TM it can still be useful while you work through the post-game content.
There are plenty of Poison types that are eligible to learn the move, but it’s best to teach Sludge Bomb to a Pokémon with a great Attack stat. This list is small in FR/LG, but some good options for this move include Nidoking, Victreebel, and Weezing.
