Instructions
Talk to the Galactic Grunt standing in front of the power plant. This starts an easy battle. After you defeat him, he will lock himself inside the power plant. He tells you that you will need a key to enter the building.
Return to the northwest corner of Floaroma Town. The guards are gone so you can now enter the Floaroma Meadow.
Walk north in the meadow. You will see two Galactic Grunts harassing an old man. Save him by battling the grunts. Afterward the old man rewards you with the Windworks Key and some Honey. Return to the town and buy several health potions and antidote for poison attacks.
Return to the Windworks power plant. Unlock the door and begin battling the Galactic Grunts. Their commander is a red haired woman named Mars. She has a level 14 Zubat and a level 16 Purugly.
Challenge Commander Mars. Her Zubat loves to use Toxic attacks. Either use potions to heal the damage or an antidote to purge the poison from your Pokemon̵7;s body. After defeating her, Team Galactic leaves Floaroma Town. Route 205 is now clear. You can pass the Windmill and cross the bridge.
