Tiny Tin

Tiny Tin is a recycled robot introduced in Volume Two(?) who works at an office.

His name could be a pun on the A Christmas Carol character, Tiny Tim, and tin.

Appearance
Tiny Tin is a red coffee can with yellow limbs and a head. He has two claws for hands and pointed feet.

His head is yellow with a sharp, jagged mouth. He has two rectangular blue eyes that are connected like glasses. The head has two tall spikes which somewhat resemble ears and a green recycling sign. His body has three coffee beans and the logo for a brand called "Morning Coffee".

Personality
Tiny Tin is somewhat of a hard worker, although he doesn't always do it properly. He sees himself as a great help, like PET, despite him also mostly causing trouble. He works at an office, where he gives reports on what he did. He's also shown to have a confusing sense of humor.

Him being a coffee can is most likely a reference to how much office workers rely on coffee.
