| Lenny Smith
| Character Information
He is a short green man, with very thick eyebrows, and a body made up of cubes. His arms are each attached to an axis, and they end in a dent, which he uses like a hand to grip objects. He has an appearance slightly similar to a Lego figure. He is always seen in work clothes, and wears the same expression every time he is seen, except when laughing or scared. From season 4 onwards, he gains a minute redesign: there is no longer a shadow highlighting the separation of the protrusion on his head from the head itself, making it less defined.
Lenny is quite friendly with his co-workers, but not too friendly to other people (like when he laughs at Richard failing to enter Chanax Inc. building because of the sliding glass doors). Although seemingly a good worker, he secretly wants to have a life of running around in the forests naked. The only reason he does not do this is because of his paycheck.
