Elmo Slide Electronic Dancing Sing A Long English / Spanish Barely used, tested. The music and motion start with a squeeze of Elmo's left hand. This 14" Elmo plushie sings, sways, flaps his arms, and glides from side to side to the super-catchy "Elmo Slide" song. It's so much fun, that kids - and grownups - won't be able to sit still when Elmo prompts them to dance with him. Fun for the whole family.
