O'Clock is a maniacal, clock-eating quokka. He wears braces and sometimes can be seen robbing clock stores to meet his assaugement. His right eye's pupil moves like a second hand. His deaths often involve disintegration or his head.

O'clock does not have much of a distinguishable personality, other than the fact his diet consists of clocks an watches. He has friends, but seems not to care much about the death of himself or others. He is known to have an obsession for clocks, and will go out of his way, stopping at nothing, in order to retrieve them.

O'Clock was part of the original cast, though he is rarely seen now.
