The Rotten Giant is a huge mushroom monster, as large as an ancient giant in size. Its skin is covered with black and green poisonous spots, and its muscle lines are full of the coldness of the Gothic style. On its giant, there are poisonous mushrooms like the sculptures of ancient temples, and the dark spikes protrude like the spires of a clock tower. The Rotting giant doesn't have traditional clothing, but its body is covered with armor formed by poisonous mushrooms and decaying plants to protect its fragile muscles. The tips of those huge mushrooms seem to be composed of patterns cast from ancient metals and black rocks.
