Boss is a wild field hamster who wears a helmet and carries a shovel. The self-proclaimed leader of the Ham-Hams, Boss has a huge crush on Bijou. He often tries to look like he knows everything, only to have it backfire in his face. He has a bit of a temper, but he is very dependable, courageous, and nice, even shy at times (especially around Bijou). Because he is a field hamster, he is more familiar with nature and is more independent compared to the other Ham-Hams. He has even developed a field hamster sense that instinctively tells him what kind of weather is approaching. However, he cannot deal with the sea as he is prone to sea sickness.
