Thonky.com's Pokémon Legends: Z-A Walkthrough

Appée asks you to hit a pile of scrap metal with Sludge Bomb to season it for her Arons.

How to Start the Mission

This mission becomes available after you talk to Mable during Main Mission 35: Reaching Rank A. Go west from the Pokémon Research Lab and talk to Appée to start the mission.

How to Complete the Mission

Open the Main Menu and go to your Boxes. Press - to go to Search, and set Known Move to Sludge Bomb, then press Y to find Pokémon in your Boxes that know Sludge Bomb. If you don't have any, Trubbish learns it at level 27. It can be found in alleyways near trash cans. Or, if you got the Sludge Bomb TM from Mabel's research level 32, you can use the Box search feature to choose Sludge Bomb in the Compatible TM field (make sure to press X to clear the "Known Move" field if Sludge Bomb is still there) and search for Pokémon that can learn Sludge Bomb from the TM.

Once you have a Pokémon that knows Sludge Bomb, have that Pokémon use it on the pile of metal near Appée.

Mission Rewards

You get 3500 Pokédollars, 5x Zinc, and 1x Power Band.
