Tango is Elmo's puppy who made her debut in the 2021 animated Sesame Street special Furry Friends Forever: Elmo Gets a Puppy. The puppy then transitioned into puppet form in promotion for the special, and in Season 52. She also stars in the recurring animated segment "Elmo & Tango's Mysterious Mysteries." She is named Tango because she loves to dance. In her debut special, it is shown that Elmo and Grover discover the stray animal in a cardboard box. On the way to a pet fair to find her a home, Elmo eventually decides to take her in instead. Her birthday is August 5th (reflecting the premiere of her debut special).
