The majority of times, Monday stays off-panel and throws things like pies, rocks and pianos at Garfield or manifests itself as an unrealistically large amount of misfortune. An example of this is when the ground below Garfield suddenly breaks open, causing him to fall in a hole. During the times Monday appears on-panel, it usually is portrayed as a hideous monster.
A prominent theme was "The Monday That Wouldn't Die", in which every day in the week after a certain Monday was also Monday.
