I assume you are talking about the Team Rocket grunt in the Celadon Game Corner in Pokémon Red, Blue, Yellow, FireRed and LeafGreen. There is no way to stop him from going down the stairs.
You can get there by going east down the stairs in Valor Lakefront.
You get to Sunyshore City by going down the stairs that was blocked at Valor Lakefront.
from lavender town you travel left and kill any one who gets in your way. then you should see two buildings. one goes to saffron. you cant get there until you get to celadon. go into the second building and down the stairs. then go up the other stairs and out. next travel left and arrive in celadon. (go behind celadon mansion once you get there and go to the top floor. then collect the free eevee from the know it alls desk). :)
You simply talk to the Rocket Grunt next to the poster at the back of the Celadon Game Corner and he will fight you. If you win, he will leave. Talk to the poster, and some stairs appear. Go down them.
its in celadon city . in the game corner talk to the guy who is covering the poster and he will battle you.then beat him and click on the poster and then stairs to the basement will open. go down . Good Luck
A lot of people ask that question, but people usually fall while going up the stairs rather then going down the stairs mainly because they do not lift their leg up high enough.
down stairs of the phenac city Pokemon center
You can find Caliban in Pokemon black. Go as if you were going to Charge Stone Cave. Stop at the mouth of the cave. Then, turn right. You should see some stairs. Go down the stairs. Turn right. Go through the tall grass. Surf on the lake. Keep going until you see a cave. Go into the cave. One of your Pokemon will need to know flash. Keep going to the back of the cave until you find stairs. Go up the stairs. Go to the far back left of the cave and Caliban should be there.
go to route 225 and keep going up. when you see a house go up the stairs and use surf. then go left and down the stairs it should be there
go down cycling path by celadon city
More bone usage going down, More musle usage going up.
The answer to this riddle is "a staircase". Of course the staircase does not actually move up and down, but when you refer to a staircase directionally, you are either going "up the stairs" or "down the stairs". Its function in and of itself is to "go" up and down.
