Singing Puppets!

I was in the store looking at those ridiculous harmonizing little toys and I thought of how fun it would be to use puppets in primary to make things interesting.  I'm thinking that to make it more appropriate and church themed I could make the puppets look like fun versions of Helaman, Sariah, Nephi, etc.  Then while singing songs the kids could use the puppets to sing certain phrases or certain parts for a duet song.  I don't know, I think it could be a fun way to let the kids use their puppetry skills and if not I can make a puppet do some pretty fun things!  P.S.  here's a tutorial on how to make sock puppets with those great wide mouths.  Click Here
