I can't let this one go by with no explanation.
A year or so ago (maybe longer) there were a couple of big civic art campaigns here in the city. The first project was fish, the second project was frogs. Large businesses purchased the undecorated statues and commissioned local artists to "interpret" them. Now, there are all these weird giant frog and fish statues all over town.
Yep, it's just that kind of place.
