As seen in the episode it first appeared in, clobhoppers were generally red in colour with two heads attached to two long necks. Their bodies were gargantum in size, despite the size of their legs. Large bumps mostly covered their back all the way down to their long tail, which was mainly used as a weapon to attack victims or move obstacles in their way.
A weak spot was proved in a diagram shown in episode 10. Since the clobhopper had thin anklebones to support its entire body, it could easily be brought down with a large vehicle and cables as opposed to the rest of its structure.
