Vardy

The Vardi were small robots which were controlled by the Emojibots. These would gaher together to make buildings as well as distribute fertiliser across the wheat.

When the Emojibots considered grief an enemy of happiness and thought of destroying it, they called upon the Vardi to kill anyone who wasn't happy, stripping them of skin, organs and muscle leaving behind their skeleton which would be used as fertiliser. (TV: Smile)
