Hundreds of trophies and souvenirs fill the rooms of the Batcave, each with a story, and one such tale is how Batman outsmarted Catwoman and her pet jaguar and prevented the theft of a valuable emerald.
One of the trophies in the Batcave is Mr. Freeze's freeze ray, which he uses to create a zone of intense cold around himself as he attempts to steal a valuable diamond necklace--and it is up to Batman to stop the supervillain.
