I am not ashamed to say that I find the slightly campy, plastic goodness of Oriental Trading irresistible. Tucked among their large selection of themed rubber ducks was 'obvious who the duck was supposed to be, but not enough to have to pay license fees' super
hero and
villain themed duckies.
Unfortunately, they don't float upright. But if you ever want a rubber duckie dressed like Bat Man, there you go.
