One Day at HorrorLand

Lizzy Morris is on day-vacation with her family. Her parents are bickering in the front while she rides in the backseat with her brother, Luke, and his friend, Clay. They're lost and can't seem to find the Zoo Gardens amusement park. Luckily their car stops beneath a horrifying billboard advertising what promises to be an exciting amusement park: HorrorLand! The family decides to scrap the search for Zoo Gardens and just go to HorrorLand.

The family quickly arrives at the park, leaving their car in the sparsely-populated parking lot. Immediately after the family makes a safe exit, the car explodes. The family races to the ticket office, only to be told by the monster operating the booth that the park doesn't have any phones. The monster, who refers to himself and his coworkers as "Horrors," tells the family to enjoy complementary entrance to the park. When the time comes, the Horrors will take care of them.

Once inside the park, their parents decide the best course of action is to quickly try to locate a phone. The adults race off to find a phone, leaving the three kids to experience a section of the park called Werewolf Village. They spot what looks like a real wolf and decide to visit a different area of the park.

The kids spy a sign while wandering the park warning: 'NO PINCHING.' Then the kids find a giant slide and go down it. Except Clay chooses to slide down the 'Doom Slide' by accident and the siblings have to go after him. At the end of the slide, they find themselves on the opposite side of the park, after having undergone a frightening experience with some fake fire.

Now rejoined with Clay, the three go into a red structure called the Bat Barn. The park is filled with a few other guests, but not too many. Every little kid they encounter is crying, and the HorrorLand Horrors try to peddle black balloons and black ice cream to the guests. The kids see some other kids go swimming in a pool filled with alligators. They get trapped in a hall of mirrors.

The kids grow tired of a park and Lizzy asks a Horror if he's seen their parents. He says he had, that they left thirty minutes ago. Then Lizzy's parents show up alive and well. Lizzy wants to leave but her mom insists that since she and their father had spent the entire time looking for them and hadn't had any fun, they should at least go on one ride together. They decide to try a ride where they float down a river in coffins. The coffins float down the river, but the twist is that the lids of the coffins close shut.

The coffins deliver the family to the entrance of the park. The lids open and the family climbs out. Dad flies into one of his patented rages and attempts to seek justice for their poor treatment. Only he can't find any employees and the gates are locked. Then a swarm of dozens of Horrors appear.

The Horrors are not costume-wearing employees but actual monsters. The monsters have been filming their adventure in the park for The Monster Channel, a cable channel seen by over two million monsters.

Luckily the monsters are good sports and have bought the family a new car. The Horrors usher the family through a door to exit the park except, they've actually been tricked into entering a chamber of terror.

The family is told they have one minute to complete an obstacle course. The obstacle course consists of a giant four armed ape creature and a pair of ten-foot cranes (birds) and some other monsters. After the minute has passed, a voice comes over the announcer claiming that only three of the five humans have survived.

But the voice meant to say five. Everyone survived. To celebrate, the Horrors lead the humans to a deadly pit where the reward is to be murdered. Before they can all die, Lizzy is struck by inspiration and pinches a Horror. The Horror deflates like a balloon. The family escapes to the parking lot, only to remember that their car exploded. So they steal a bus. When they arrive home, a Horror jumps out from the back of the bus and hands them free tickets to the park.
