You see where I'm going, several animal+theme Pokemon are incredibly popular specifically for their simplicity and readability. And your Pikachu/Dedenne comparison doesn't really work, you got them backwards. Pikachu is quite literally just an electric rat, Dedenne actually has a whole antenna motif to it so by your logic it should be more popular, but it isn't.
