CGI Twiddlebugs on Sesame Street

The Twiddlebugs, a small family of insects that live in Ernie's window box, have been a stable of Sesame Street for decades. Traditionally, they've always been conventional puppets, but the show's newest season has been featuring new CGI versions of the Twiddlebugs this year.

I'm not sure if these CGI Twiddlebugs were created with conventional 3D animation, or if they are actually created using digital puppetry like Elmo's World. Does anyone out there know for sure?

Either way, things have certainly come a long way since the good old days.
