Trumpkin is the dwarf who helps the Pevensies find Prince Caspian in Prince Caspian. He is a Red Dwarf and one of the Old Narnians resisting the Telmarine occupation.
Trumpkin begins the story as a practical, skeptical warrior. He supports Caspian after the young prince escapes from his uncle Miraz, the usurping king. Alongside the talking badger Trufflehunter and the Black Dwarf Nikabrik, Trumpkin helps Caspian gather the creatures of Old Narnia and organize a resistance.
Miraz’s soldiers capture Trumpkin and transport him toward Cair Paravel, where he is to be drowned. The Pevensie children arrive in Narnia after Susan’s magic horn summons them. They rescue Trumpkin, and he leads them toward Caspian’s forces. His role is especially memorable because he initially doubts that the ancient kings and queens, and even Aslan, will truly return.
The wrong options are other Narnian characters. Reepicheep is a courageous Talking Mouse, Dufflepuds appear in The Voyage of the Dawn Treader, and Nikabrik is another dwarf who ultimately turns to dangerous magic. Trumpkin later becomes an important leader in Narnia.
