What is the name of the weasel thief who steals night howler bulbs in Zootopia?

The weasel thief who steals night howler bulbs in *Zootopia* is Duke Weaselton.

Duke Weaselton is a small-time weasel crook first encountered when Judy Hopps catches him robbing a flower shop. He later sells bootleg DVDs from a street stand. Judy and Nick track him down because he sold night howler bulbs to Doug, the sheep secretly processing the plants into a dangerous serum.

Duke does not understand the full conspiracy at first, but his transaction becomes a crucial link in the investigation. When Judy and Nick question him, Mr. Big’s threatening presence persuades Duke to identify the buyer. The character’s name is also a joke: it references the Duke of Weselton from Disney’s *Frozen*, another role voiced by Alan Tudyk.

The name is often remembered in the wrong order as “Weasel Duke.” The official character name is Duke Weaselton, and he is a thief, bootleg seller, and supporting antagonist rather than the mastermind behind the night howler plot.
