Exploding flying plant.
Durable plantform seeks enemy targets and flies toward them, exploding on con- tact. The Shredder spends most of its life in the earth. When agitated, it will spring from the ground, then begin to fly toward its foe. Should it reach its target, the Shredder will explode with considerable force, releasing a cloud of thorns as it does. Shredders are resilient, but can be eliminated with concentrated weapons fire.
