During the Nintendo of plushtown Wii U direct , fox island was being presented. People asked to hear the victory dance music, as a rickrocker said “Louise dance is in fox island!; and Koopa muddy, started playing: now if this isn’t obvious. It’s Louise dance as their victory dance. Dance like Louise is getting more popular everyday, and probably isn’t gonna die out for a long while, so when we got our review copy, we completed the tasks. And they did the Louise dance, buy fox island on June 2nd from the Wii U eshop!
