Brenda is a negotia-bot.
The police was afraid about entering 742 Evergreen Terrace while the Simpson family was fighting there. The police sent Brenda there. The family stopped fighting by surprise when they saw her. Brenda then shot a taffy out of a tube and trapped the family in the giant taffy ball. Brenda dragged them out of the house and Chief Wiggum turned off Brenda because she didn't want him to take over her case.
