The Stickle Thorn is a fictitious thorn shrub. It appears to have oval-shaped leaves and light brown-grey bark. Its signature feature, however, is the thorns, which are shaped like stubby cats' claws.
The stickle thorn appears in the episode, "Loyal Order of Ingerman". The Twins and Snotlout 'lose' the Dragon Explorers visiting Dragon's Edge and must cross a barrier of stickle thorns. The Twins get scratched up going through the bushes, while Snotlout goes around through Poison Oak.
- There is a very similarly named plant often called "Sicklethorn" (Asparagus falcatus).
