Gregoriah is a humanoid creature belonging to a fictional species known as zum’ae with primarily navy blue fur. He has one sharp, upright horn on the left side of his head, with two bands - one cyan and one orange - wrapping around it. The same pattern can be found above his hands, which resemble paws. He can be depicted with some tufts of navy blue hair on the right side of his head. He has paw pads on the undersides of his hands.  He has big, heavily lidded eyes with yellow sclerae and pupils and orange irises. He has blue tusks, blue round eyebrows, a yellow tongue, and an orange triangular marking on his face. He is depicted wearing a black graphic tee with a blue circle, a red circle, and a white triangle on it. His pants appear to be baggy cyan jeans. He wears sneakers that are black, white, and orange. On the Fun Flood at Squishy's floor, Gregoriah is seen coming out of a small black and green TV, wearing a white shirt with green stripes and green suspenders with a pin of Squishy on one strap. He is also seen as a 3D model at the top of the obstacle course through a window into a control room, where he is frantically running around in flash steps and touching buttons.
