I've just gifted 8 different hats to our long time adventure squad members. If you come on an adventure with us, you get to join the duck race. Since everyone is a little yellow duckie, racers are encouraged to put on a duck hat. As best I can tell, these are the hats most commonly worn by these adventurers.

Here are all the "quack"-cessories
While there are over 8,000 user-created wearables in /dcl , I was not able to find acceptable versions of all the duck hats.

@billytea and I have toyed with the idea of releasing our own versions of the missing hats:
bucket
valkyrie
traffic_cone
baby_duck
firefighter

Technically there isn't a fez in the DCL marketplace but I found a reasonable substitute. All the other ones are in the marketplace and I think that's pretty cool.
