Some beloved members of Sesame Street were welcomed to The Masked Singerneighborhood on Wednesday.

The family friendly episode kicked off with familiar faces Elmo, Big Bird, Cookie Monster, Count von Count, Oscar the Grouch, and more singing BTS' "Dynamite." As has been the case with the other themed nights, the characters appeared in various capacities throughout the episode, including giving clues, rooting for contestants, and heckling Ken Jeong (Oscar tells the panelist at one point, "Don't feel so bad, I want you to know that your guesses are always my favorite. They get the audience booing and there's no sweeter sound.")
