Princess Donut is a prize-winning Persian cat who enters Dungeon Crawler World with Carl and becomes a talking crawler, spellcaster, performer, and leader. She is not a sidekick joke; she is one of the story's main characters. Donut's power is social as well as magical. She understands audience attention, status, language, insult, performance, and loyalty in ways Carl often does not. That makes her valuable in combat, sponsorship, public relations, and alliance-building. Her royal persona becomes part of how the party survives.
