What are Mr. Avery's physical features in To Kill a Mockingbird?

Mr. Avery lived across the street from Mrs. Dubose's house and was known to sit on the porch all evening and sneeze. Mr. Avery is the overweight neighbor who has a rather large stomach. In Chapter 8, when Jem and Scout build a snowman, they pack mud and snow around the center of the snowman until it resembles Mr. Avery. When Atticus sees the snowman, he tells Jem that he needs to make some adjustments because it is a caricature of Mr. Avery. Jem solves the problem by putting a pair of hedge clippers and a sun hat on the snowman to make it resemble Miss Maudie. Later on in Chapter 8, Miss Maudie's house catches on fire, and the neighbors attempt to save her furniture. Mr. Avery bravely enters the burning house and begins throwing mattresses and furniture through the window. After the neighbors begin screaming for him to exit the building, Mr. Avery attempts to climb out of the window. He gets stuck in the window for a brief moment but manages to wiggle his way out. Once he climbs onto the second-floor porch, he slides down a pillar, crashing into Maudie's shrubbery.
