Meta Mice Underground

The mutant species of mice from the planet Rodentia have been attacked in recent years. For the past decade, Felines, a cat-like species from a nearby planet, have been conquering Rodentia, pushing the mice deep underground. In a desperate bid for survival, the mice have devised a method of transporting their physical selves into the MetaVerse using modern technology. They've successfully moved 4,000 mutant mice so far, and they're hoping to save the rest of the population soon.
