When arriving at Invite Only in the 1990s, specifically Taye and Li'l T's childhood home,
Both Usagi and Ranma in Female Form were wearing Michael and Madonna's 90's outfits.
Taye welcomes them in with Li'l T stating that they were able to figure out the moves and later on came up with their own entitled "The House Party".
Just as they start to show off their moves, Lima urges them via Boomy to stop by reminding them to "respect the time-space continuum".
"She's Right, You Know." said a familiar voice
It was Setsuna...She along with Haruka and Michiru with Mousse and Ryoga had time traveled with them.
Female Ranma and Usagi danced their way through the 90's song only to unlock The Macarena as its own craze.
Once they figure out the craze, they take the sisters back to Dance Central Intelligence where it is having an emergency. Li'l T thinks that cleaning up the house would have stopped it and consequently not get her worried of what will her and Taye's parents say about the party they left behind. Taye clearly states to her that she was not yet born at the time to receive a response from their parents, then she asks what is happening in the headquarters.
