CMO

CMO is a rectangle-shaped talking robot with a face on his screen. CMO is a mini-version of BMO.

Personality and traits
Very little is known about CMO because it has only made a small cameo in one of the episode, as it appears briefly in "Puhoy," where it falls from Jake's truckload of pillows and bounces off BMO's head. Besides BMO saying “Oof!” CMO is not mentioned, explained, or acknowledged. CMO is sexless, just like BMO. CMO's name, presumably, is pronounced "See-Mo".

Appearance
CMO is similar to BMO, but is smaller, grey-to-beige in color, and with only a slot for an optical disc and a black dot next to it below its screen instead of BMO's buttons and controller port. CMO also has a similar face/screen to BMO. On the side of it is the word CMO in there the same way BMO does with the word BMO. CMO's arm comes out of the letter O the same way BMO's arm does with the word BMO on it's side, although the O in CMO is a little too low down and a bit moved off to the side so it doesn't perfectly line up with the C and the M. CMO's arms and legs are darker than the rest of its body. They are a brownish grayish color, the exact same color as the word CMO on its side and the line for the disc. CMO's voice sounds exactly like BMO's only it's slightly higher pitched.

Trivia

 * CMO was stated to appear in an episode that would discuss BMO's backstory, and would also feature AMO, which was described as "Death Star-sized." While the episode never made it to production (or has yet to air), CMO was recycled for later use.
 * In the episode "Hug Wolf", when Finn was tied to a chair, there was a hollow tree in the background with a white machine in it with a screen on it and a line under it that looked similar to CMO. Coincidentally, when the episode Puhoy first aired, "Hug Wolf" aired right after it.
 * When CMO falls on BMO's head, if you listen very closely, you can actually hear CMO's voice. It is almost exactly like BMO's only a bit more high pitched.
