One of my favorite stories was the star struck lover Grape-kun and his waifu Hululu. Grape was a 21 year old penguin who recently passed away. He was made famous for falling in love with a penguin clothed anime girl.
The animal clothed anime girls were used during a promotion. It was unexpected that Grape would fall in love with Hululu. They had to remove her just so he’d eat since he was love sick. When the promotion ended Grape and Hululu’s fans banded together to keep the pair together (and won).
However Grape fell ill and eventually passed away. He was with his Hululu til the end according to zoo staff.
