Meet Gunther Tanaka, the world's most questionable scientist. Driven by a budget that screams "desperation" and a curiosity that screams "madness," Günther decides that "Premium Dog Delight" is a perfectly acceptable lunch. Spoiler: It really wasn't.
After a bizarre diet consisting entirely of dog kibble, rat food, and salted nuts, Günther transforms into a biological disaster zone. He sprouts tails, develops oversized rodent teeth, and gains the involuntary, highly inconvenient superpower of uncontrollable high-pitched squeaking. What follows is a chaotic, panic-inducing flight from Tokyo to Osaka, pursued by paranoid Russian drone-pigeons and his own crumbling sanity.
His grand journey eventually reaches its peak: he evolves into a massively obese, gluttonous giant rat-monarch. He is now comfortably retired in a remote cave in Timor-Leste, where he spends his days being the undisputed king of rocks, shadows, and silence, waiting for the next tourist to wander in so he can unleash his signature squeak.
