What country are the three naked bears from?

Let's Naked Bear is a very interesting animation. The main characters of this animation are three bears. What is the status of these three bears in human society? In fact, there is an episode that expounds the life of three bears when they were young. When they were young, they were three little bears. Cubs used to be kept as pets. It was just that people didn't understand the language of the bear at that time, so no matter how much the bear begged, it was still not adopted.
