“Par-ty par-ty par-ty!”
The Lady Robot was originally built to be a toy, just like the Clockwork Robot. But as soon as her cogs and gears sprang to life, it was clear that there was something that she liked even more – and that’s PARTYING!
Nobody else can party like the Lady Robot. She never gets tired or runs out of energy, and thanks to her new and improved self-winding key, she can dance to the music 24 hours a day, 7 days a week. She’s even got a built-in karaoke machine. Some day she might decide she’s ready to stop partying…but not yet!
