Originally, only one Dinger was used primarily, but others have since appeared. The original Dinger was employed as a bellhop at The Furry Arms Hotel, appropriate since his own bell could be rung for service (usually provided by Benny Rabbit).
There are at least three different Dinger puppets:
- Sesame Street
- The Muppets Take Manhattan
- Sing Yourself Silly!
- Big Bird's Birthday or Let Me Eat Cake
- Sesame Street Jam: A Musical Celebration
- Sesame Street: 25 Wonderful Years
- Don't Forget to Watch the Movie
- 123 Count with Me
- The Adventures of Elmo in Grouchland
