I like the Fluffets, see a lot of places you could go with them IF (and that's a big if) you:
-Get the camera a bit farther away. (I couldn't understand what was happening)
-Make a puppet stage that you can hide behind, AND:
-Get some other performers. (I know your secret. How? The fact that there's never more than one character in a scene at once.)
All in all, pretty good!
And one final note: It's not the puppet, it's what you do with it. Keep using sock puppets.
Thanks for taking the time to listen.
Hope this helps,
