Toilet Shark follows three young women as they plan to have a slumber party. Their boyfriends show up and the shenanigans begin. They decide to play with an Ouija board and accidentally summon an ancient demon shark! Much to their dismay this “Toilet Shark” is fierce and not taking any prisoners. By the time they realize what they have done it is almost too late as the bodies start dropping! The girls call upon their uncle, Plumber Dave, to save the day. Will he? Or is this toilet shark going to swim through the neighborhood plumbing biting everyone in its way!
