Who is the most popular Sanrio character? Well, that's what I'll be talking about in today's blog post! When people think of Sanrio, they automatically think of Hello Kitty. Of course she would be the most popular character, right? Surprisingly, she's not! And she hasn't been for at least the last five years. Instead, that spot has been taken by Cinnamoroll. The cute little white cinnamon puppy has charmed fans for five years, making him the most popular Sanrio character. It's actually very surprising to see how popular he is, and Sanrio has taken notice of his popularity. They're making more merchandise for him than ever, which is making fans very happy. It's amazing how a little puppy can become more popular than even Hello Kitty herself. Regardless, I hope you all still enjoyed this blog post!
