Some knowledge of the Simpsons is required to complete the puzzle. All answers are recurring characters from the show. No special guests appear. Adjacent refers to all neighbouring cells, including diagonals. Surnames are only accepted when no one else shares the surname, or when attached to a title e.g. Chief Wiggum would be accepted, but Simpson would not. HINT: When Homer says everyone is adjacent to a core Simpson, he means everyone, including himself and all other core Simpson family members.
