Tokyo Ueno Zoo had training for animal escape accident. This year zebra escaped.By the way, they are serious.
Anyway one of the popular souvenir of Ueno Zoo is "Panda Ramen", it is non- fried instant ramen with soy sauce suop which is made by Fujiwara Seimen. Originally Fujiwara Semen made Sapporo Maruyama Zoo's "Polar Bear Ramen (salt soup) " first and it got be very popular and made good sales, so they made each local big Zoo Ramen series now. Besides these, there are Osaka Tennoji zoo Tiger Ramen (Curry soup), Fukuoka Zoo Felis silvestris Ramen (tonkotsu soup), Koyto Zoo Gorilla Ramen (Soy sauce soup) and Chiba Kamobaga sea world Orca Ramen (salt). I have tried Polar bear only but I promise, it is very good.
When you go to the super market, you will find another series of animal ramen. it is Kirin (Giraffe) Ramen made by Ogasawara Sifun. Comparing to Zoo ramen series. Their history is old and they released it in 1960'. Kirin Ramen's taste was different by color. Red is soy sauce, Blue is salt, Brown is miso soup. Penguin one is sea food soup and Capybara one is soy sauce one with yuzu flavor. Why Capybara? I don't know. They made Flounder Ramen before and it has Curry soup. Because Flounder is called KAREI in Japanese and Curry and Karei sounds similar to Japanese. So They don't have deep thoughts to name it. You will see a kind of ZOO in a super market's Ramen shelf. lol.
Ah! You may find this one too "Beware of bears" Ramen. It was made as Hokkaido speical.
