They shrunk themselves for fame—and got hunted for food.
In what may be the most unhinged genre mashup of the year, Mouseboat Massacre (2025) crashes ashore as a dark comedy slasher with a rodent-sized twist and a boatload of blood. Directed by Jordan Downey (The Head Hunter), this cult-bound horror oddity doesn’t just wink at B-movie madness—it gleefully gnaws through it with razor-sharp teeth.
The story sets sail when a group of social media influencers boards the S.S. Poppin’, a luxury miniature cruise yacht designed for eccentric billionaire and pet enthusiast Roland Tibbets (Steve Buscemi). Intended as a quirky PR stunt—a "tiny luxury cruise for the world's tiniest passengers"—the boat is engineered for rodents: mouse-sized hallways, hamster-ball lounges, and gourmet cheese buffets. The twist? The influencers must shrink themselves to fit.
But when the experimental nanotech that shrinks them malfunctions mid-ocean, the guests find themselves trapped at mouse scale—with no way to reverse it. And worse still, something else is on board: a genetically modified lab mouse, escaped from the cargo hold. Codenamed “Echelon-9,” it was bred for intelligence, speed, and territorial rage. Now, it's loose. It’s hungry. And it remembers who caged it.
What follows is a fever-dream survival horror as the shrunken humans fight their way through air vents, flooded tunnels, and the dark inner walls of the boat. One by one, they're stalked and shredded by the monstrous mouse. Blood splatters across dollhouse chandeliers. A broken toothpick becomes a spear. And cheese? It’s bait.
Both absurd and atmospheric, Mouseboat Massacre embraces the surreal horror of scale, turning everyday objects into tools of terror. Think Honey, I Shrunk the Kids meets The Descent—with fur and fangs.
Because this isn’t just survival. It’s vermin vengeance.
