Aqua's excited. He's heard a little bit about Halloween and he's excited. A night of meeting new people and delicious treats and children in cute costumes. They all get to be like Aqua for the night! Well, the opposite of Aqua, to be a little more accurate. They put on their cute, colourful pelts for a short time to become something different than they normally are, and then shed them at the end of the night to become human again. It's like a temporary connection he has to the general public for a night. He really likes that.

His excitement and over all lack of a sense of timing means that Aqua arrives a little early. When Snake arrives, Aqua is sitting on the edge of someone's lawn (not in costume) and watching all of the trick-or-treaters pass by with just the brightest smile on his face, waving to a few and chatting with others. Mostly just to comment on how cute they look, since he doesn't want to keep them from their treat-focused goal for the evening.
