Royal Penguin/Manga

Canonicity
As this instance of Royal Penguin only appears in the splash page of Chapter 17 her actual existence within the Kemono Friends universe is uncertain, as these pages do not necessarily represent the actual state of things within the universe.

Existence in the Manga's Original Serialization
The Japari Library has yet to confirm that Royal Penguin was not added to the manga retroactively in the printing of the second compiled manga volume, 18 days before the airing of the 8th episode of the Kemono Friends anime.
