I have been working on an as of yet unnamed game project that has recently required some bodd falls/impacts. Step in Norbert. Norbert is several phonebooks an argos catalogue and some rolled up newspapers wrapped in a faux leather jacket. The arms, neck and bottom of the jacket have been taped up as well as the zips. This was done to try to deaden the sound and stop any unwanted paper/zip rattles.
Norbert has so far survived being thrown down the stairs and into a wall with some interesting sound results.
He has yet to be thrown out of a third storey window.... but he will be.
