Rolling Vine

These plant creatures appear to be bundles of vines all round-up and wound together, forming a plant ball, which rolls along the plains or any (somewhat) flat surface. What few creatures realize is these are in fact semi-sentient plant creatures, and can be quite menacing if threatened.

 SPECIAL ABILITIES

Entrap - these rolling webbed balls try to bite anything that moves towards them, if their attack hits treat as being webbed. Small creatures that have grabbed a creature inflict a -2 attack or saving throw penalty if they bite onto the upper body. If they bite the lower region, they inflict a cumulative 20% reduction in speed. They continue to bite, inflicting damage until the creature collapses, then they release them.

Rollers look like an artificial device, similar to a vine or branch that has been twisted to have a rounded appearance. In fact, these are a semi-sentient plant that forms itself into a ball, so it can roll for both transportation and to roll away in a defensive action.  Normally they are spread out against the ground, somewhat similar to a starfish sunning themselves, but when any creature or potential threat nears them, they ball up and roll themselves away. If they or their allies are threatened, rather than roll away,  they head towards the danger, attempting to trap their opponent.

They can build up quite the speed from rolling down a hill, these plants have tiny tendrils all over their bodies, they use these to push themselves to gather speed or even climb up surfaces, albeit very slowly.

What many creatures are not aware of, that like many other plants is that Rollers never stop growing, so that these much smaller creatures are common, there are much larger, stronger, faster and keener.
