I understand now. This is a zerg with a harpoon. He can pick out units out of hiding and cut them on the front spikes. He has two acid gun, shooting at long distances. And he has two bone saws the sides of the body (working with the help his swirling tendons). Same he can produce a live fence of thorns, when Gigling eats bowels of enemies. They can move slowly and make difficulties for movement infantry and light military vehicles. Sorry for my English.
