In this song, Grover wakes up one morning and sees a monster in his mirror (his reflection). Instead of being scared, he sings, "Wubba wubba wubba wubba, woo woo woo." The clip features a number of camera tricks, such as a sequence in which a full-body Grover walks in front of a mirror showing his animated reflection. At the end of the song, Grover has his arm around his reflection.
In Season 22, the song was re-edited to include cameos by celebrities who had appeared on the show that year, including María Conchita Alonso, Candice Bergen, Ray Charles, Chubby Checker, Glenn Close, Tyne Daly, Geena Davis, Bo Diddley, Roger Ebert, Whoopi Goldberg, Jeff Goldblum, Kadeem Hardison, Charlayne Hunter-Gault, Bo Jackson, Kid 'n Play, Robert MacNeil, Lou Diamond Phillips, Julia Roberts, Gene Siskel, Jeff Smith, Tracey Ullman, Blair Underwood, Malcolm-Jamal Warner, Robin Williams and The Simpsons.
The album verison of the song includes an additional verse of Grover and the monsters scatting. These vocals can be heard in the celebrity version when the celebrities start singing.
The celebrity version was included in the specials Big Bird's Birthday or Let Me Eat Cake and Sesame Street Jam: A Musical Celebration. A clip from the celebrity version was included in Sesame Street's All-Star 25th Birthday: Stars and Street Forever.
