Hey Pandas, When Was The Monet You Realized That Cartoons Are More Closely Related Than You Originally Thought?

I was watching Straight Outta Nowhere: Scooby Doo Meets Courage The Cowardly Dog, and realized that Courage's mom or whatever his female owner is called looks like a crossover from Scooby Doo Meets Batman's Mrs. Baker and Granny Tentacles from Spongebob: The Movie. There's another cartoon where she looks exactly like someone, but I can't remember it right now.
