A pair of backup singers accompany Grover in episode 4525 of Sesame Street. They appear from nowhere within Hooper's Store to provide backing vocals on Grover's song, "Grover Can Do It All." Alan is surprised that Grover has brought them in. "Did you not hear the lyrics?," Grover replies. They accompany Grover on his reprisals of the song and later, Grover lets Mando borrow them for a song of his own ("One Thing at a Time"). The green monster was previously used as Karina the Ballerina. Both of their outfits are recycled from the show's Glee parody during season 42.
