Queen Regina is the queen of Ka-Larry, a fictional land in The Wubbulous World of Dr. Seuss. She is first mentioned in "Who Are You, Sue Snue?," where Jane Kangaroo is holding a special event for her, which Sue Snue apparently ruins when she mixes the ice cream and cake (which later becomes the hit of the celebration). Jane later attempts to hold another party for her in "Halfway Home to Malamaroo."
