Chief Mark is one of the secondary characters in Baby Lamb & Friends, and is the chief police officer of the Capitol City Police Force.
Mark has a yellow complexion and wears a blue police uniform with a gold badge, as well as a black utility belt. He also wears a blue police chief hat with a gold badge on it, though he is shown to be bald whenever he doesn't wear the hat.
Chief Mark can be a real stickler at times, often not crazy about doing stuff that is considered fun. There are several times in the series where he never got to enjoy something so he ends up imposing unfair rules on people thinking that just because he can't enjoy it, neither can others. But eventually people convince him and he experiences a change of heart. He is also a fan of Cliff Hanger. But he also has a soft spot, and also has a huge crush on Officer Patricia.
