Smiling Gary is always cheerful and happy, and seems to look on the bright side of life. He is a main character in Klay World: Off the table.
He was the one who first discovered the Peach aliens on his radio, so he got to come with on the truck. He also seems to chuckle at everything, regardless of it being funny or not. He likes to eat other Klaymen as kabobs. Though he is positive with everything, others seem to think he has an attitude.
In Klay World: off the table he says "The aliens started talkin to me" and " its problably just the aliens, giving us something to drink".
