Actually cute little bunny manju, a Japanese treat made of flour wrapped round sweet bean filling. I stumbled upon these just as I was about to head out for the night, but thanks to an excellent blog named The Food Librarian, you get to dream whether to eat these or make squee-ing sounds of joy. Bunny cakes here! Mmmmm.
-- Addendum: Rabbits and the moon go back to a legend from India telling of a bunny that hopped into a fire so starving people could eat, and was transported to the moon as a reward; as the story traveled over time and place, the Japanese version had the bunny pounding rice flour, or mochi.
