After falling in love with a standee of Hululu, the penguin character featured in sleeper hit Kemono Friends, the Humboldt Penguin known to us as Grape-kun has passed away according to tweets from the official account of the Tobu Zoo, one of the zoos that participated in the initial Kemono Friends collabooration events run while the series aired earlier this year.

Grape-kun was initially moved out of his normal habitat on October 10th, with the Hululu standee at his side as workers observed changes in his physical condition that required him to be removed from the exhibit. Rest in peace Grape-kun.
