In Disney's 1953 animated feature film Peter Pan, the Lost Boys are a ragged collection of young boys headed by Peter Pan in Neverland. The Lost Boys' names are Marmaduke and Binky, Slightly, Nibs, Twins, Cubby, and Tootles.
Nibs (Rabbit) is the group's most active and boldest member. He's dressed as a bunny and doesn't say anything. He may be the least important Lost Boy, with the fewest speaking roles (excluding Tootles of course). Thomas is revealed to be his real name in the book series. His last name is kept a secret.
