Emil K. Gammelplassen is a naturalist, explorer, and author of several wilderness safety guides. He appears in the Hilda Tie-In Series. The character is unique to the novelization and does not appear in either the graphic novels or the animated series.
Emil's appearance is not described in the text, and he is only featured in one image, where he can be seen reacting to Jellybean entering Scout Hall. On this image, he appears to be a fairly young man, dressed in a Sparrow Scouts uniform.
Throughout the novels, Hilda frequently mentions Emil and his various books.
In "Hilda and the Nowhere Space", Hilda is forced to hide in a hollow tree to escape Jellybean after encounteirng him in the woods one night, and remarks that Emil would not approve of her doing this.
Near the end of the story, Emil appears in person as a guest speaker during the Sparrow Scouts badge ceremony. He ends the ceremony with a speech in which he recites a poem about adventuring. When Jellybean unexpectedly enters Scout Hall and causes panic, he, along with Raven Leader, urges people to stay calm, to no avail. He is not seen again after Jellybean leaves Scout Hall to chase Hilda and Tontu.
Despite the fact that he wrote multiple books to warn people about the dangers of the wilderness, Emils is a true explorer who loves the wilderness. Hilda agrees with his views of how being in the wilderness makes him feel alive, or how getting lost is just another adventure. He also reminds everybody a the ceremony that they have nothing to fear, but feat itself.
