I honestly have no idea. There are, like, a dozen call duck owners on the forum, I have no clue why you guys fixate on Wobs. Is he unusual for a duck? I admit I've got no baseline so I have no idea if the things he does are normal or not.
We fixate on him because you keep posting adorable videos. If you'll just go ahead and send him to me, I'll stop fixating online and do it in person instead.
