Build-a-Bear revealed its next Sanrio stuffed animal is a Hangyodon plush, and this time the character is only available in a bundle. It is also an online exclusive so, while it can arrive unstuffed and undressed, it can’t be picked up at a store. It costs $68.50.
This is a situation in which you get multiple stuffed animals of Sanrio characters when buying the Build-a-Bear Hanyoudon bundle. In addition to the merman, the fish comes with Sayuri the octopus. As a smaller toy, she always arrives already stuffed and doesn’t include any cosmetic accessories. Hangyodon himself has scales embroidered on his chest, if you don’t have him dressed. The Hangyodon Sleeper pajamas that come with have both the fish dude and octopus all over them.
Here’s a closer look at all the different photos showing off the stuffed animal, plush, and outfit.




This is the second online-exclusive Sanrio plush in a row. Back in June 2025, Build-a-Bear announced My Sweet Piano would join the collection. She also arrived with an outfit. Both her and Hangyodon became more prominently featured and known in larger communities as a result of their inclusion in Hello Kitty Island Adventure.
The Hangyodon Build-a-Bear Sanrio plush bundle is now available online and includes a Sayuri stuffed animal.
