I can summon my personal pet and I also found my message in a bottle. So far I haven't found the engraving tools and my underwear hasn't talked to me yet...
Yeah, I could pick the trunks in character creation, but so far they seem like only a cosmestic addition (though I heard they're supposed to talk).
I didn't write a custom message so I got the default from the bottle (which is fine), also wasn't inspired on the undead front, but I'm curious to see what names more inspired people have come up with.
Btw, the pet, how do you summon it? Can' t say I've noticed it yet (but I only saw the mail asking to pick a graphics on the day of release so maybe it will end up in a later patch, hope I won't have to restart then though)
