Ah yes, how I love the Simpsons. While the dancing figure doesn't quite fit how I remember the dancers from the episode, it's quite clearly the same type of deal. And for some reason, I got a strange urge to join the navy...

The ones from the Simpsons wore bikinis if memory serves me

And they didn't have purple hair, but apart from that...

I'm sorry, bujt are they even wearing shirts on their tops?

I think they're wearing some sort of covering (not a shirt though). You can see the straps when they turn sideways
