The Twiddlebugs seen most frequently on Sesame Street are a family of four. These Twiddlebugs often find themselves facing difficult challenges, such as taking their car to the zoo or hanging a postage stamp on the wall. Presented with such daunting situations, it would an easy thing for them to simply give up, and indeed they express despair when their initial attempts at solving these problems meet with agonizing failure. However, the Twiddlebugs persevere in the face of adversity, and through collective brainstorming and cooperation, they always manage to overcome even the most seemingly insurmountable tribulations, such as figuring out how to exit a roller rink. These moments of triumph are cause for celebration for the Twiddlebugs, who remain blissfully unaware that their ultimate solution is rarely the most logical.
A secret of Twiddlebug reproduction is revealed in the Sesame song "Let's Lay an Egg". "Snails do it, slugs do it," two gastropods sing. "Even tiny Twiddlebugs do it!" the Twiddlebug family (only without Timmy) chirps. "Let's do it! Let's lay an egg!"
The main Twiddlebug family consists of:
- Thomas Twiddlebug (Papa Twiddlebug), performed by Jim Henson
- Tessie Twiddlebug (Mama Twiddlebug), performed by Frank Oz
- Timmy Twiddlebug (son), performed by Richard Hunt
- Tina Twiddlebug (daughter), performed by Jerry Nelson
Other Twiddlebugs have appeared in books, including Mayor Thaddeus Twiddlebug. The Twiddlebug species is seen in great numbers and a wider variety of colors, and different aspects of Twiddlebug life and culture are examined therein. Other Twiddlebug homes and communities exist in other windowboxes on Sesame Street. Twiddlebug Town is located in Elmo's windowbox.
The CGI versions of the Twiddlebugs are animated by Magnetic Dreams.
Performing the Twiddlebugs
The high-pitched effect of the Twiddlebugs' voices was accomplished by recording the performers at slow speed, then playing the vocal tracks back at normal speed. The characters' very deliberate enunciation is a result of the performers' attempts to keep the dialogue comprehensible after it was sped up.
In addition to being Muppets, the Twiddlebugs first appeared in computer-generated form in Sesame Street 4-D Movie Magic. Additionally, new computer-generated Twiddlebug sketches premiered on the show starting in season 37. Magnetic Dreams animation studio, Nashville, adapted the Twiddlebugs for CGI. The CGI versions of the Twiddlebugs also made a cameo in an advertisement for Sesamestreet.org. The CGI versions are all voiced by Rickey Boyd.

| Family Photo|
|The family tries to take a family photo, but someone is always missing (as they are operating the camera). When they all try to take the picture they finally get it to work, by photographing themselves in the mirror.|

However, Tina uses the paper clip as a music stand, and Timmy uses it as a backscratcher, and Tessie uses it to mix her batter for a cake. When everything is back to normal, Thomas prepares to go out, only to find that it's a nice sunny summer day.|
| Flat Tire|
| The Twiddlebugs are off to Uncle Ollie's surprise birthday party, when they suddenly get a flat tire. Now they have to search for something to replace it. Thomas suggests that either a triangle-shaped nacho or a square-shaped cheese cracker would work, but the cracker gives a bumpy ride, which breaks the nacho. But a red checker does work, and they're off - not realizing they left the cupcake behind.

- In the Who's Who on Sesame Street coloring book, the characters are incorrectly listed as Thomas (father), Tina (mother), Teddy (son) and Tessie (daughter).
- The Spanish version of Sesame Street, Barrio Sésamo, translated the names of the characters as Los Nabucodonosorcitos, literally "The Little Nabucodonosor's", for King Nebuchadnezzar II the Great of Babylon, called Nabucodonosor in Spanish.
- The German version of Sesame Street, Sesamstrasse, called them Krabbelkäfer, which basically means "Crawlingbugs" or "Scuttlebugs".
- Most of the time, Twiddlebugs are depicted on TV as miniature creatures, small enough to live in a window box. However, in an early segment, Kermit the Frog counted "happy little Twiddlebugs" at a Twiddlebug Party - most of whom were bigger than Kermit.
