Kura Sushi Zenmai Toy Ochinai-kun (Doesn't Fall Down) Tuna Tuna Egg Salmon Shrimp Due to the aging of the mainspring, it barely runs. It runs about 5cm. One of the tuna toys has a different sound when the mainspring is wound, and it only rotates without moving forward, so I think it's broken. For those who can disassemble and repair it, and those who understand, please consider. (_._.)_
