Snot Wheels is a company owned by Nelson, and invested in by Lisa, that does up bikes and makes them look better. It becomes very successful and Nelson also hires Seymour Skinner. It eventually went broke and stopped when Nelson found out he was using a glue that dissolves in water and everyone's bikes fell apart.
Behind the laughter Edit
Snot Wheels is a parody of Hot Wheels both in name and logo.
