[Black/White] Where is the third dancer in Castelia City?

Question

In Castelia City square in Pokemon White, there is a breakdancer who asks you to find two more people to dance with him.

I found the first one, in one of the long roads leading up to the square, but I can't find the other one!

Answer 1

One breakdancer is on the street in Castelia, like you said.

The second is at the North part of the city, by a fountain.

The third is by the pier in the southern end of the city.

Find all three, and they'll reunite by the fountains. Talk to the dancer in the middle will grant you an Amulet Coin, if I remember correctly.

Answer 2

Here are 2 videos showing where 2 Dancers are in Hiun city.and the other one is where the last one is
