Throne

As with Lozenges, the Throne's "hostile" label is a misnomer (as of right now, anyway). Typically spawning in the upper echelons of the world like Moon, Thrones simply roll along the ground, albeit at half the size of a Lozenge, and with much more rapid movement speed. While Thrones can't jump, their rate of acceleration (given enough ground) tends to send them flying. These vermin can be identified at a distance by the dim red glow they emit.
As non-hostile things, Thrones quickly flee in the opposite direction when attacked — there are a lot of comparisons to be drawn between Thrones and Lozenges in general.

Be careful when using a rope tool on a Throne, as they tend to flail violently around you when hooked. It won't damage you, but it can send the Throne flying in a random direction.
