Play Mutation of J.B. Online
You wake up as a pig-man in your cousin’s lab, clicking through bizarre rooms, grabbing random junk, and trying to make sense of puzzles that involve fishing keys out of toilets. The dialogue’s pure ‘90s cheese, and the whole thing feels like a weird dream you can’t look away from.

Game Overview
Ever had one of those days where a quick visit to your cousin spirals into getting turned into a pig-man and chasing a mad scientist across space? Yeah, that’s basically Mutation of J.B. in a nutshell. You play as Johnny Burger (yes, really), who signs up for some sketchy experiment and—surprise—it goes horribly wrong. Next thing you know, you’re clicking through weird, pixelated rooms, picking up random junk like a half-eaten sandwich or a rubber duck, and trying to figure out how any of this will help you stop being part pig.
The puzzles are just the right kind of ridiculous—think "use a fishing rod to retrieve a floating key from a toilet" levels of logic. And the dialogue? Cheesy in that perfect early '90s adventure game way. It’s got that janky MS-DOS charm where the graphics are barely holding together, but somehow that just adds to the weirdness. If you’ve ever lost hours to games like Day of the Tentacle or Sam & Max, this one’s a hidden gem worth digging up.
Just don’t blame me when you catch yourself muttering "why won’t this monkey take my dentures?" at 2 AM.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
