Clay is at the Driftveil City Pokemon Gym.
Clay uses Ground-type Pokemon, so his Pokemon are weak to: Grass, Water, and Ice
Clay has a Krokorok, Excadrill, and a Palpitoad.
On Pokemon Black and White, Clay has Krokorok level 29, Palpitoad level 29 and Excadrill level 31.
Ditto
After you beat Clay in Pokemon Black and White,he said that you have to go to Route 6 and into Chargestone Cave.
Driftveil City
beat pokemon gym leader clay,take on route 6, go through chargestone cave,then you'll be at the 6th gym.
You go to the cave that has the spiderweb on it and Clay comes along and blasts it with his Krokorock and you can go in but heal your pokemon first the cave is invested with team plasma
My guess is about 40.
its clay as a gym
Yes
you go to the cave that has the yellow wed in front of it and clay will destroy it for you to pass
