Twig is a small, white deer-fox. He has black antlers on the top of his head and has a long, bushy tail, and some spots on his back.
In his younger days, his antlers were little more than two tiny bumps on his head.
Twig is a protective, trusty and brave animal who likes to help Hilda. When he is protective, he goes in front of Hilda and growls at anyone that she doesn’t know when they go up to her. However, he can also be scared, as seen in "Chapter 1: The Hidden People", when he gets scared by a troll. He also isn't too fond of Water Spirits, as proven in "Chapter 7: The Lost Clan", when he refused to come along with Hilda and Frida when a water spirit gave them a ride to the island of the Lindworm.
He is usually quick to realize something is not right, or a certain person/creature cannot be trusted. He has a sharp sense of smell; he was even able to follow the scent of a Marra despite her ability to teleport.
Hilda loves Twig very much. He has been her pet since before the start of either the graphic novel series or the animated series, and is very loyal to her. He will try to defend her even against bigger opponents or if he's outnumbered.
A flashback in "The Deerfox" shows that the two met when Twig was trapped underneath some rocks and young Hilda saved him, after which he returned the favor by rescuing her from an eagle, but in doing so got separated from his Deer-Fox Herd.
- Twig's antlers have been said by David to be pointy and were able to hold their own against a hit from a garden spade, implying that they are much stronger than they look.
- In the original publication of Hildafolk, Twig had blue fur, a white underbelly, and white antlers. He can still be seen as such in the hardcover release of Hilda and the Troll, but he was recolored for the paperback version.
- Hilda gave Twig his name based on how his underdeveloped antlers reminded her of little twigs.
- In a community stream on May 21st, 2020 at 11PM ( GMT +0 ), director of television series, Andy Coyle, confirmed that Twig is yet to be a fully grown deer-fox. This was proven correct when "Chapter 9: The Deerfox" showed what adult deer-fox look like.
- The book "Hilda and the White Woff" claims that Hilda first met Twig five years ago, but after she rescued him it wasn't until two years later that he returned the favor and became her pet. The animated series does not state how long ago exactly they met, and both events happened on the same day.
