Pretty papers might work for Washi.

My Pet Spite has some sea/sailor related in their TC. Poseidon and Nautilus, too but their profiles are broken so don't be surprised by the mess.

I completely understand the the equal parts love and angst toward the new naming system. I am glad you were able to make your pet ideas though. :)
It seems like there have been many good suggestions for Washi. Love the story by the way!
So here are some suggestions for your sailor.
[edit]I'm still adding to this list accidentally hit post before I was done. Ok so I am stopping here.
Is your sailor a pirate, a lover of sea life, a collector of sea flotsam. Hopefully some of these suggestions work.
For the everyday Sailor
Pirating is the Life for me

And since I like to read to my pets.
Something to read at sea
[item=Hidden Treasures: Beaches]
Things I started to add and left off. Some duplicates of items in other colors or derivations. For the sea lover/collector: All seashells For the Pirate: All jewelry, all alcohol (especially ones from Rathskeller Inn), For Books: the Encrusted Book series, anything related to weather, water, oceans, sailing, seashells, jewels, treasure, gold, and sea/aquatic life.
Ok so in my search for ideas I may have gone overboard :) my sister thinks I should stop because half the fun of creating a TC is finding things for it. Not sure I agree with her but then I don't really collect TC's. One thing I have realized though is that your sailor pet might need a less broad theme than sailing and a love for the sea at least in its TC. Though if you can afford to collect all this and more I wish you well and I look forward to seeing it.
Good Luck!
PS Have you thought about employment. Davey might make a good Scuba Instructor for the Beach Shack.
