 When Luna checks out the arcade and enter her password is, I love  tuna fish and fieldmouse pudding. In the original, the password is:  the rabbit of the Moon pounds rice. This password refers to Serenas  Japanese name Usagi Tsukino, which means rabbit of the moon. The  Japanese have a legend about a rabbit in the moon that makes mochi  (pounded rice) much like the European/American legend of the man in  the moon. (episode 1.05 "Computer School Blues").
