Hard vs Soft

Inflatable tube man has soft body and it acts depending on the blower.At the entrance of the store,we can often see the inflatable tube man swaying its head, arms and body slowly.If the blower could work harder,the wind would be stronger and the tube man will shake like mad.

And then,let it wear hard armor and stick blades on its hands.Now，we have an inflatable tube solder who can't attract but can defend very well.The inflatable tube solder don't have legs so it can't move.But if you put it in front of the gate, the solder will wave its blades insanely and without certain.So when enemy wants to beat it,he can't guess how the inflatable tube solder will fight.So the enemy will never defeat it.
