if they are disconnected in any way (ie, they are two seperate meshes joined as one) then you can go mesh > seperate (or is it modify mesh > seperate, i just click the seperate button on the shelf...)

if that doesn't work then you've probably accidentally hit the extrude button when all faces were selected and didn't move anything
in which case you're just going to have to go through all the faces and kill each one.
alternatively, instead of selecting each face one by one you can use the paint selection tool or change the selection settings in the selection tool attributes, much faster that way

also, you should make each face four sided, if you were animating kiro then you'd get better deformation in the mesh
