Grape (16 April 1996 – 12 October 2017), colloquially known as Grape-kun (グレープ君, Gurēpu-kun), was a Humboldt penguin (Spheniscus humboldti) at Tobu Zoo in Miyashiro, Saitama Prefecture, Japan.

His attachment to a cutout of Hululu, an anthropomorphic Humboldt penguin character from the 2017 anime series Kemono Friends, earned him international fame and an online fan base.

[3][4] Midori and Grape-kun hatched a chick together, but the zoo removed the baby, citing inbreeding as the reason to separate it from its parents.

[5][3][6] In April 2017, Tobu Zoo placed 60 cutouts of characters from the popular anime series Kemono Friends around the grounds to attract visitors.

[7] The cutout placed in Grape-kun's enclosure, Hululu, was an anthropomorphic Humboldt penguin[8] and was part of a campaign to help visitors learn more about the animals in the zoo.
