A small scallop puppet.  The body was a cheap party favor with the inside sculpted, eyes added and sculpted on, and then molded.  This was for Natural Bridges and there were going to be a whole choir full of them.  The mouth is operated by a simple trigger that pushes up on a clear acrylic rod running through an aluminum tube that pushes up on the top of the shell to open it.  The handle is just 3 pieces of acrylic sandwiched together.
