Mr. Chompers is a bulldog owned by Grey's neighbors. In November 2017, Grey began dogsitting Mr. Chompers since Grey's neighbors had to work and Mr. Chompers was still too young to be left alone for several hours. In "H.I. #93: Mr. Chompers", Grey announced that he had begun dogsitting Mr. Chompers, a nickname he had given to the bulldog due to the dog's habit of biting people's hands. Aside from images of his paws, no images of Mr. Chompers have been released yet.
