Roperite

The Roperite is a creature from Lumberjack Folklore. It’s the size of a horse with a long prehensile muzzle that can be used as a lasso. Often they have rattles like a rattlesnake, which they shake when they hunt. Typically, they catch rabbits, but may go after people. They run off after capturing them and drag them through the thorns until the prey dies. No animal is fast enough to outrun them, and they can go over, around, or through any obstacle.
