As for why the title is "Smile", if you look at the photo, I think you will agree with "I see". The photo is Yawara. You won't know if you really felt good until you ask Yawara, but your open mouth looks like a big smile. Yawara has a personality that likes to be alone who doesn't like fights too much. There were no other bears around at this time, and it was after bathing, so maybe he was in a good mood?!
Other bears may also look troubled when a snooty partner is nearby, or they may look refreshed and cheerful after bathing. Please pay attention to the bear's facial expressions. 【Zookeeper: Ito】
