Oooh, I've found a video on Youtube showing all the dances from Fortnite in real life, and there's a fantastic one called 'Best Mates'.
I'm going to try that one, but I'm not sure I can do it.

When younger, I used to dance like anything. Does anyone remember the Slosh?

When the village children come out of school, (they often come to chat to me on my garden bench in front of our house) I'm going to ask them to demonstrate all these new dances for me!
