very violent monster in a box!

[zombieman]

Hello I am not sure what all I need to purchase to make a very violent monster in a box effect... What I want is to be able to have my create hanging by chains in a warehouse scene we have and have it violently moving and shaking like something is beating against each side trying to get out. any light anyone can shed would be much appreciated.
