Green triangles, red cylinders: Japanese soup

At the 7-11 in Japan in winter, you can get hot soup.  You use tongs and a ladle to chose from among some 12 cages in hot broth.  If a clerk helps with the slippery exchange, you can name the shape--if you know it or can read. The descriptions are written for triangular grey green herb gelatin; weiner; egg; tofu.  

Or you can point.
