In Seattle, you can find random Pigs on Parade (artfully decorated statues of pigs) scattered throughout the city. For a while, I didn't realise this was a 'thing', until I went to Vancouver last year and saw that they had Eagles on display throughout the city.
Apparently, this phenomenon extends far beyond North America as I found out in Rotorua, on the North Island of New Zealand. Each summer, they have a fish exhibit, called Fish Out of Water. I noticed the first fish in the Tourism Center, and then was able to find 4 out of 6 in just an afternoon. Without even searching them out!
