I have this pet peeve where I absolutely hate it when cartoon animals never act like or reference the animal they are ever in any way, shape, or form. It doesn't even have to be a big thing. Like, if you have a character who's an anteater and you make a 150 episode series with him, and in one single episode he's eating a stick of celery with raisins an peanut butter (colloquially known as "ants on a log") then that's enough, that's something. But why ever make them animals if they're essentially humans in big animal onesies?
I remember the movie Fritz the Cat, based on R. Crumb's comics. Ralph Bakshi didn't want the characters to act like animals at all, even a little, to the point where he changed something from the original comics to fit that vision. There's one scene where Duke the crow saves Fritz from falling off a bridge, and he does it by flying. But since in the movie the crows can't fly, because they're just humans in crow suits, he has to do it a different way. That's the kind of shit I can't stand. Like it was THERE and he took it out!
Sometimes I think the writers of the shows forget that they're writing for animals, or that scripts are written for humans but then sold to shows where the characters are animals. Like, there's this episode of My Little Pony Tales that irritated me, too (only playfully this time.) MLPT bugged me anyway because the ponies were always bent into awkward human shapes, sitting like humans and holding things in their hooves somehow. I liked how Lauren Faust made it a point to adapt the world to how a pony might build it, instead of forcing ponies to fit in a regular human world.
Anyway. This episode of MLPT was the old "kid thinks they might actually be the child of royalty," where the king and queen are looking for their lost daughter and Patch fits the description given, and she was adopted when she was little so there's a chance this is possible. The description of the Princess is that she has pink hair (not mane, hair!) yellow eyes, and a birthmark on her hoof (side note- Patch's birthmark turns out to be just paint and, like, did she just never look at that hoof before? How could she think she suddenly had a birthmark? Silly pony.) It turns out the real princess is another orphan who wasn't adopted, but they didn't know it was her because she'd dyed her mane blue at the time.
But, like… When you're trying to identify a pony toy, what are the first three things you notice? Isn't it mane color, body color and flank symbol? Patch and the princess are both pastel yellow, true, but Patch has a patch on her flank and the princess has a rose. And this is G1, so ponies are born with their symbols. The king and queen would have known what color she was and what symbol she has. Not to mention, their carriage is pulled by Clydesdale horses who never speak and might not even be sapient. You know, like a human king and queen might be.
So when I turn on, say, Bluey to keep me company and the kids do things like bark or wag their tails when they get excited, it makes me smile. It's such a little thing. Side note, I also like when Bingo asks Mum, "How do animals without tails know they're happy?" and Mum doesn't actually say the answer, because kids will hear that and get excited because they know the answer, and when little kids can answer questions that grown-ups don't it makes them feel good. Smart thing for a kid's show to do.
