Gustavius Boles is a fictional character from the musical 93 Million Miles in a Balloon.
Unlike the original character, this version of the character is a cat and not a dog, and he also has slicked-back hair. His outfit has also changed; from a brown coat, black cap, white ascot and flying goggles to a black business suit and a bowtie.
