Tawawa

It's a bit surprising that no one attributed the spider to Revan. While the difficulty with other options is understandable, I might have chosen Lok for that image myself (it was about 50/50 for me), but the spider is a completely obvious choice.

Well, I agree with Alex, Revan has always expressed arachnophobic sentiments. It turns out, this applies to not all spiders, as he explained.
And the fish was some kind of Southeast Asian fish; I figured the person who sent it was a fan of local fauna or sushi (although sushi isn't made from freshwater fish, but who knows).
