It is being reported by Deadline that Fox has renewed Grimsburg for a third season. Coming with a handful of episodes left in its sophomore run, the pickup is the first post-premiere episode order for the animated comedy, which was already renewed for Season 2 ahead of its 2024 debut.

The series is set in the deadly little town of Grimsburg, where self-proclaimed "world's most smartest detective" Marvin Flute, voiced by Jon Hamm, has returned to crack its most disturbing cases. But there's one mystery he still can't solve — his family. In a town where everyone has a secret, Marvin must follow every lead in order to redeem himself with the ex-wife he never stopped loving, even if it means hanging out with the son he never bothered to get to know.
