The first lady gave "the platypus walk" a try on Saturday during a visit to Disney World's ESPN Wide World of Sports Complex.
The dance was inspired by Disney's "Phineas and Ferb" show, whose characters include Perry the Platypus.
It required some flapping of flippers, or arms if you're human, shuffling left and right and yanking limbs up and down, all to a pulsing rock beat.
Mrs. Obama did the dance at an event marking the second anniversary of her "Let's Move" campaign against childhood obesity.
