As a baby/child/person with easy access to them, I used to snack on Koala's March cookies like there was no tomorrow. What's not to like about these biscuits? They're poppable, cute, and tasty. A great snack, especially for little hands and people who appreciate bears doing cute things stamped on to their cookies. There were only two flavors available in the USA back in my day, chocolate and strawberry. I was all about the chocolate, of course. Apparently, there is a flavor in America now that is like a reverse koala--chocolate cookie with white chocolate creme inside. I think I would've liked that one best, but alas, not around back then. However! I've made up for lost time by snatching up these Koala no March straight from NapaJapan, in the flavor 'Custard Cream Puff'.
Fact is though, that these Koala cookies are meant for kids, so maybe I'm expecting a little too much from them in terms of taste. An adult palette might be able to tell the difference between custard and vanilla cream, but for a kid the exciting bit is probably that the koala is wearing a chef's hat this time around.
These were perfectly tasty, but not radically different from other teensy bear biscuits that have came before it. If they were available as a flavor here in the UK, I'd get them before strawberry, but maybe not before the classic chocolate. This won't stop me from buying every other milky custard variation that comes out in Japan though, but I'm kind of a sucker.
