I would recommend Bee and Puppycat if you didn't watch this show yet. It has a cute art style in my
opinion and also an interesting story. You can watch all episodes for free on YouTube (+ also the pilot
episode), new episodes are about to coming out soon this year.
Another show with a more "cute theme" is the anime Onegai My Melody. It's a show based on the
Sanrio character My Melody, Kuromi also has a big role in here and there various seasons out. I
watched some episodes back then on YouTube, not sure if there are still available there. Besides
as far as I know, there is no English dub out, so only Japanese with English subtitle.
A cute show I've been watching again and again is a show called Hilda (on Netflix).
I think the story is decent, it's not over the top but has a very calming scenic backgrounds and music. There's mystical creatures, but it's not just focusing on the kids in the show, adults know about the creatures as well; so it feels natural all around.
I also recommend Bee and Puppy Cat as that was a very fun watch.
I enjoy watching cartoons and recently came across "Bluey". It's about a family of dogs. The stories are so spot on about real life issues & the characters are all well written.
I echo Bee and Puppy Cat. Would We Bare Bears also be considered cute? That's a good one(though I haven't seen it in ages)! Probably some others that I'm sort of on the fence about whether you could call' em cute or not!
Most of my favorite shows are preschool/?baby? shows, which are usually considered ?cute? by default. One of my favorites that?s currently running is the Muppet Babies reboot. It has pretty animation and visuals, some clever writing, and the morals are good for what they are. I feel like a lot of preschool shows now lack the heart and soul of the ones from a decade or two ago. I believe Muppet Babies is one of the exceptions and deserves more attention, especially since people keep saying Disney is treating the Muppets badly.
Bluey is another one I like, but it was already mentioned.
Baby Looney Tunes.. I already love Looney Tunes by itself, so the baby version of it
is just so adorable, I could watch it all day, especially Baby Taz Q___Q
There's this new cartoon by Disney called Amphibia and I absolutely love it. It's about a girl who mysteriously ends up in a land full of frogs and makes a home there. I think it was actually made specifically for me, lol. It's so colourful and cute, and it has good humor and lessons as well.
