Osotam has a long, white snout, with huge eyes. He only has a small black dot as his pupil. He also has triangular shaped ears that stick out to the side. He has a rather wide body with a white chest and stomach. He is covered with a brown fur. His white hands and feet are barely visible because of his fur. Overall, he appears to resemble a fish-ape-dragon hybrid.
Osotam was the twenty-eighth monster to fight Godman.
