What is this thing in my soup?

It's been a few days since I wrote anything but that's because I don't really have much going on. Today I have to pack and go to the grocery store. Exciting! And then I'll make some kind of stir fry for dinner. While I was thinking about what to make for dinner, I started wondering if they would even have the things I need at the store down the street. I don't know how easy its going to be to find fish sauce, but considering that the only "ethnic" foods they have are taco shells, I'm not counting on them. But this brings me to another question that has been on my mind for a few days...
What is this thing in my soup?
The white thing with the hot pink edge.
It wasn't meat. It wasn't a vegetable. It was some kind of firm gelatinous salty thing. It wasn't tofu, either. And why the hot pink? It didn't taste bad. It just tasted like broth. Still, I only nibbled it and then made Mike try it so he could also be confused.
It is of Japanese origin. I still have it if you want it.
