If you loved Zatch Bell! 101st Devil, try One Piece: Chopper auf der Insel der seltsamen Tiere
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.

Zatch Bell! 101st Devil

One Piece: Chopper auf der Insel der seltsamen Tiere
Was sie teilen
Both films are directed by Junji Shimizu, and they both carry the playful mood tag, and they sit in Action / Adventure / Animation territory. If that's the register that drew you to Zatch Bell! 101st Devil, the second film will land in a comparable space — through a different lens.
What One Piece: Chopper auf der Insel der seltsamen Tiere is
You wash ashore in a riot of geysers, landing alone on an island where the animals crown you king. While your crew searches the far shore the horn hunters arrive, bowing to a violinist who chews horns for power and eyes the island’s greatest treasure. The animals taught you something about fear you’re about to teach him.
