On the third day of her tour to promote the second anniversary of the Let's Move! Initiative, the wife of President Barack Obama slipped into her exercise gear to encourage kids in the area to get active.
Watch Michelle Obama dancing on stage with professional choreographer Rosero McCoy below:
The 48-year-old - who is mother to two children, Sasha and Malia - told her young admirers: "You guys know I love to dance but I haven't completely gotten the dance down so I'm going to watch you alright?"
Wearing a zip fastened hooded top and trainer shoes, she performed the Platypus Walk, a dance inspired by the TV show's character Perry the Platypus.
MIchelle was accompanied by Disney Channel stars Debby Ryan (Jessie), Roshon Fegan (Shake It Up), and Disney XD stars Doc Shaw and Kelsey Chow (Pair of Kings) and Olivia Holt (Kickin' It).
Phineas and Ferb has been a hit around the world - with nearly one in two kids in the UK tuning in - and has secured guest appearances from stars including David Beckman, Jamie Oliver, Michael Douglas and Selena Gomez.
