The Timid Tabby isn't actually scary if you're familiar with Dungeons and Dragons, where multi-headed and multi-limbed creatures commonly appear throughout the games and novels.
My's was either Switchin' Kitten and Buddies Thicker than Water, there where both scary cartoons to go back to, it was hard to choose, but I had to choose Switchin' Kitten.
It was definitely Blue Cat Blues, the plot of the episode escalated to be extremely dark, thus, someone would be like "Why does this exist in the first place?" It's because they do.
