Various Japanese zoos have been collaborating with Kemono Friends and hosting special events. It's been working, as social media has been showing an increase in zoo visits. The Tobu Zoo was hoping to bring otaku and children alike to their exhibits, but they accidentally turned one of their penguins into an otaku...
Each exhibit pairs a Kemono Friend character with their real life counterpart. Grape-kun, a 20-year old penguin, literally fell in love with Hululu, who is a Humboldt Penguin character.
The zoo keepers are isolating him from Hululu for his health. It turns out, Grape-kun wasn't eating his food because he was too busy chilling with Hululu. Grape-kun is 20, which is elderly for a penguin, so his cute antics could cause him to die from malnutrition.
