We could have the snails eat the patients one by one until they are all dead, except for Ward. After the first patient is eaten the rest think Ward has become a cannibal so they band together to collect a stool sample of Ward’s and in a big scene, you see all of them sifting through the poo looking for human hair. They use their bare hands and get poo all over them; their hands, faces, hair, clothes, furniture, drapes, a chair leg, an exhaust fan mounted in the ceiling, a .. oh, got carried away.
Anyway, in a twist, we learn that the head doctor of the mental ward is actually stark raving mad with a gigantic unibrow that looks like a furry caterpillar boinking his forehead. He has a passion for escargot which explains all the snails running around the ward. His master plan to take over the world hinges on growing humongous snails, so he feeds his patients to his crazed snail horde. The audience sees that the snails are growing quite large from feeding on human flesh, but they’re still pretty small and seem unthreatening.
That is, until the last scene when we see the crazy unibrow doctor walking into his office and behind the door is this snail that’s over 7 feet tall. The office door slams shut and you hear these horrific screams. Next, you see a camera panning along a big slime trail on the carpet that leads all the way outside and into the woods. The movie ends with everyone wondering why they paid 10 bucks to see this, and if Ward II, Slime is a Crime, will come out next year.
