The bears, aged just a few months old, were pictured by physical education teacher Valtteri Mulkahainen, in the forest in Finland.
Mulkahainen witnessed the magical moment while traveling through eastern Finland and ran into bears near Suomussalmi.
Brown bears are shy creatures who avoid contact with humans. They are the largest omnivores in Europe and the Finnish national animal.
“The cubs behaved like little children,” Valtteri told. “They were playing, and even started a few friendly fights. I felt like I was on a playground in front of my house, where small children frolic around. That’s how much they reminded me of little children. At one point, the three of them got up on their hind legs and started pushing each other. It was like they were dancing in a circle.”
