Compost

Compost is a teenager and an animal rights activist.

History
He and his friend Solar Panel helped Bart and Lisa to get into Abbattoir and Costello LLC. to save Bart's cow Lou.

Personality
He and Solar Panel seem to be tolerant to much, because of their apologizing to "mother fence" before they cut through it. They both are probably vegans too, because of their passwords "milk is murder" and "cheese is genocide".
