Zebramounts appear in the reference book, The Incomplete Book of Dragons.
Based on the Zebramount's rendition, their name derives from the striping along their bodies. They are a small Riding Dragon that appear to have a dark orange or brown color with black stripes. The image also shows large protruding teeth from the lower jaw, and one pair of wings. They appear to be quadruped.
Zebramounts are used for riding, often as a young Viking's first riding dragon. They are easy to ride due to their easy-going nature, but it can be tricky to get them to move.
During the Dragon Rebellion, Zebramounts sided with the humans.
Zebramounts are discussed in this reference book, and appear in the 'Dragon Key' at the back of the book.
