During a roleplay game where Kaeloo and Bad Kaeloo are pretending to be the rest of the main four as well as themselves, Kaeloo refuses to play with Bad Kaeloo if she hits her too hard. Why is Bad Kaeloo hitting her so hard? Because she's used to "playing" with Mr. Cat, a masochist who enjoys pain and wouldn't tell her if she was hitting "too hard".
Kaeloo tries playing one of Stumpy's video games, only for the other players to cruelly bully her. One player even asks "Why do you exist? You suck!" Now think about how Stumpy spends his time playing video games every day.
