Four years ago a Japanese penguin in Tobu Zoo fell in love with an anime cutout. That penguin's name was Grape-kun and was previously suffering from depression and barely eating after his wife left him for a younger penguin while he was ill and quarantined. In 2017 Grape-kun started to court with hululu, a cutout put into the enclosure as part of collaboration promotion for an anime. This garnered alot of attention in Japan as Grape-kun's overall mood increased and he started to eat again without a handlers help. Sadly, Grape-kun passed away on October 12th, 2017 but he didn't die alone, Hululu was by his side until the end and reportedly died peacefully. In honor of the best year Grape-kun had lived in a long time, a new cutout of hululu and him now sit in the enclosure.
