I needed Tozo to have a companion/side-kick so that he wasn't constantly talking to himself as the story progessed. Thought balloons are useful but not very dynamic.

Klikker is meant to provide Tozo with someone he can converse with, but who won't overshadow him. He is effectively an appliance, with a fairly blank personality though he'll develop quirks as time goes by.

The first sketch (above left) gives an idea of the blankness I was trying to get, but was a bit too 'generic cartoon robot' for me. The second attempt (middle) made him more appliance-like. I was thinking 'iPod' here. However, the minimal stylings don't fit the overall aesthetic of Nova Venezia and the beady eyes and perma-smile were a bit chilling too. The final design (right) is effectively the same but with steam-punkish brass and verdigris additions.
