However, when angered, his color is inverted, with his eye turning black, outline turning white, and yellow turning glowing red, although his form can change to that which is desired at will. A tapestry hanging from the wall in 'Northwest Mansion Mystery' depicts him as black or ash gray instead of yellow and with a red-eye. In 'The Last Mabelcorn', he appears for a few moments as black with a yellow eye.

As seen in the finale, he also sometimes changes colors when distressed.
