Pet Penguin in Japan
There is more information about this little guy after the video.
Here's some additional info. The penguin named Lala is apparently a male penguin despite its name. He was caught injured in a fishnet in Kagoshima prefecture, Japan about 22 years ago. The family seen in the video nurtured him until he fully recovered. Since he refused to leave the family, the family accepted him and build him the little airconditioned room. He lived on for 10 years with the family until he died of old age in 1996. Within the town he lived in, he was well known (not really a surprise i guess) and the path he'd take to go to the fish store was known as the "lala-chan road" and people would spray some water on the road during hot days in the summer to protect his little feet from burning on the concrete.
adding on: In case you were wondering how the penguin eats fish at the store without paying like i did, the owner family would go to the fish store and pay the tab for the penguin
edit: Sooooo, apparently there was some coverage on a tv program aired on the 19th of February 2020 about lala and the caretaking family's current state. I haven't been able to look at it but it seemed that there was a lot of information that I couldn't get my hands on a year ago(my excuse is that I had to dig up old web blogs and forums on the internet that were hard to verify), that proved a bit of the above info wrong. Specifically, the cause of death seemed to be pneumonia instead of old age. Cool new information also came out like how lala would occasionally just go out of the house without anyone noticing and end up at the local train station so that the station would call the family to pick lala up at 6am etc... Hopefully someone will upload the clip somewhere so I can get my hands on it.
