Just rereading the manga and stumbled across this page then decided to make a thread on the numerous symbolic references of the moon in the manga.
^Here we see Gaara mentioning "he" (Ichibi) gets blood thirsty during a full moon

^Here the full moon once again the night Itachi murdered his entire clan

^The night of the Kyuubi attack, a full moon once again

^Another bloody night

And last but not least:

It seems to me that there is a connection throughout the manga with violence, the mangekyo sharingan, and bijuu all tying into the full moon some how. Perhaps because of the sealed Juubi? Im sure there are plenty of others i couldnt remember i just find all the symbolism with the moon to be very interesting.
