Takumo soseji stretchy sausage

The Takumo Soseji (Tako-sosi, or Octopus Sausage) is a popular Japanese bento box garnish. It is a sausage with the bottom half cut into "tentacles" so that when cooked, they curl outward, making it resemble a little octopus. It is a cute, creative staple often included in children's lunches. [1, 2, 3]
