Rubber duck collecting - until recently I didn't realise it was a thing. But sure enough, it is.
Ever since the first floating rubber duck was created in the 1940s, designers have been creating their own versions, and people have been collecting them. TV characters like The Simpsons have been immortalised in rubber ducks, as well as various super-heroes.
Speaking of super-heroes, in New Zealand our super heroes are often sports stars. And the only designer rubber duck that I know of is our very own All Blacks Rugby Rubber Duck. He sports the All Blacks Rugby official logo on his front, and a rugby ball beneath his wing.
