As a Sanrio fan, I found this show is very entertaining and of course, very cute! I like how the art style is not really your typical 2D/3D animation and it uses clay stop motion I think (?), making it a unique animation style. The story itself revolves around the slice of life of the characters, their daily live and such. Since they're targeting children the story is pretty simple, funny, there's not much conflict happening. There's Birthday episodes, and Halloween, and Christmas. There's not much happening in the story itself and very little character development, but I enjoyed it very much because of the cuteness ofHello Kitty, Pompompurin, My Melody, Cinnamoroll, and Bad Badtz-Maru!
