Koala's March

Koala's March (コアラのマーチ, Koara no Māchi^?) is a bite-sized cookie snack with a sweet filling. Made by Lotte, the product was first released in Japan in March 1984, and was released in May 1990 in the United States as "Koala Yummies".

Koala's March is in the shape of a koala with a picture of a koala on the outside of the cookie doing various activities. The filling comes in various flavors, such as honey, vanilla, cafe latte and banana. The two most common flavors are strawberry and chocolate, and are two of the flavors available in the U.S., along with white chocolate and matcha creme-filled chocolate cookies. The snack also comes in pineapple flavor, though it is rarer than the other flavors. Koala's March supports the Australian conservation group Australian Koala Foundation.

They also have cards, naming the different types of "koalas".
