The GoroKongu looked much like the ShodaiKongu, still covered in brown fur except for the face, chest, hands and feet, and with the most noticeable difference being the suit's head. The head is now bigger, with bigger eyes, mouth and a shorter neck. The suit's arms are longer, and more hair covers the hands. Its legs are somewhat shorter, but the feet show no considerable difference. The suit also seems to be somewhat top-heavy.
- To make the suit feel more ape-like, poles were put into the arms of the suit for the suit actor to hold on to. This also helped the suit actor make more natural movements with the suit's long arms.
- By the time the suit was needed for Go! Greenman, the poles had been removed. Because of this, it was harder for the suit actor to make realistic movements. Throughout the episode the suit's arms would flail around very unnaturally.
- A second GoroKongu head was created for closeup shots of Kong.
