Smelly Grungy is the daughter of Foul Grungy and Pig Grungy and the sister of Bug Grungy. She likes to listen to music but her brother, not so much. Smelly let Egon and Ray in under the pretext they would blow up the Firehouse. She asked they start with Bug's room. Eventually, she lost interest and returned to Bug in Egon's lab. Smelly danced along to the music machine but when things got out of hand, she asked her parents for help.
- Smelly is a parody of Lisa Simpson. Her fascination with music may be a reference to Lisa's saxophone-playing.
