I will use a character that I rigged as a test-dummy and never really used for much ... called him mumbohttp://www.xdv.org/mmm/cgpics/mumbo/mumbo1.4.jpg
the idea is having a scene of several mumbos, they are all together playing differnt things - happy playarea.
the voice you dont see. perhaps a shadow, but I think this is not even necessary, but you see the reaction of these bunch of playing mumbos, when theire names get called ...
lets see what it gives.
I will take a bit of time before the voice starts ... but not much, just some seconds to show theyr happy together before "Clatto! Verata! Nn(coughcough). Okay then - that's it"
