"I'm the calm one in the Morris family. Everyone says, "Lizzy, you're the calm one."
The main characters of One Day In Horrorland and Return to Horrorland, and the narrators of the Goosebumps Horrorland books Escape From Horrorland and The Streets of Panic Park. Lizzy's family got lost on their trip to Zoo Gardens Amusement Park and discovered Horrorland, where they were almost killed by the Horrors. Ever since, Lizzy, her brother and their friend Clay keep getting involved with the Horrors for the sake of stopping their twisted plans.
- Adaptational Dye-Job: Lizzie says that she has black hair in the books but she brown hair in the TV series.
- Arbitrary Skepticism: Luke laughs at Evan's claims about Monster Blood in Return to Horrorland despite having escaped a theme park run by monsters.
- Annoying Younger Sibling: Luke, as he is full of energy and enjoys pinching people, particularly Lizzy.
- Brainy Brunette: Lizzie is brown-haired, and runs a whole journal load of information she personally found out about of Horrorland.
- The Bus Came Back: They return for the Horrorland series, with Lizzy being the POV character in Escape from Horrorland and The Streets of Panic Park.
- Cassandra Truth: Most of the Very Special Guests are not entirely trustworthy of the Morris siblings because they think they might be spies for the Horrors. It turns out however that of course Lizzy and Luke are the trustworthy ones. The twins Jillian and Jackson were unwittingly acting as The Mole for the Menace and attempted to make the Morrises The Scapegoat. Lizzy realizes they've been trying to fool everyone when she catches Jillian lying.
- Foolish Sibling, Responsible Sibling: Luke's the foolish and hyperactive one to Lizzy's responsible and level-headed one.
- Forced Transformation: Lizzy is briefly transformed into a pumpkin in Escape from Horrorland.
- The Leaders: Of the Very Special Guests in the last two books in the Horrorland series, due to their prior knowledge of the theme park.
- Older and Wiser: Although they're only a year older in the Horrorland series, they return to Horrorland to help out the rest of the kids escape.
- Only Sane Woman: Lizzy is considered the "calm one" in her family.
- No Sense of Personal Space: Luke likes to pinch Lizzy and their friend Clay, calling himself "The Mad Pincher." It comes in handy when they realize the "No Pinching" signs in Horrorland were there for a reason...
- Too Dumb to Live: Luke has shades of this in Return to Horrorland since he seems too eager to try out the rides at Horrorland despite the fact that he knows they are potentially lethal and that the Horrors tried to kill him and his family the last time they were there.
Horrorland Horrors
Portrayed By: Jason Hopley, Neil Crone, and Ron Stefaniuk (TV)
The Horrors are a race of horned monsters who run the deadly theme park Horrorland. They make a sport out of tormenting humans with their dangerous rides, hidden behind jokes and puns to lull their victims into a false sense of security.
- Amusement Park of Doom: Horrorland, which is actually the image for that page.
- The Bad Guy Wins: In the TV show. It's implied they actually kill the Morris Family by driving their car off a cliff.
- The Dragon: In the video game Escape From Horrorland, the Horrors as a whole are this to Madison Storm who, in the game's continuity, is the actual creator of the park. In Goosebumps Horrorland, Byron is this to the Menace.
- Evil Is Hammy: Oh so very much, especially in the TV show when the Morris Family is put through "Raw Deal" and the Horrors really get to show off how hammy they actually are.
- Heel–Face Turn: Between the original books and Goosebumps Horrorland, the Horrors seemed to have stopped actually killing humans and now just operate an actual theme park. But there are still some Horrors who ally themselves with bigger threats, and it hasn't stopped park management from hiring dangerous people like Jonathan Chiller.
- Heroic Sacrifice: In the TV series, the one good Horror who tried to save the Morrises from being eaten by Ripper dies so they can get away. Unfortunately, it doesn't do much good when it turns out their car is now being controlled by the other Horrors, making this a Senseless Sacrifice.
- The Leader: In One Day at Horrorland they were led by a female called the Horrorland MC, while in the video game they were led by Madison Storm. Another video game designated a Horror closely resembling a carnival barker and calling himself Horiffico as their leader.
- Our Monsters Are Different: They are a race onto themselves. The Horrors vary in terms of skin color and horn size, and some have human like features such as hair and breasts while others don't.
- Token Good Teammate: There was a random Horror who tried to warn the Morris Family to get out of the park while they could in One Day at Horrorland. In the TV show, he actually saves them from being eaten alive by Ripper.
- Took a Level in Kindness: During the Goosebumps Horrorland series, it would at first appear that the Horrors are the ones who've orchestrated the many villains to get their revenge on their child adversaries. It's actually the Menace of Panic Park, alongside a small handful of Horrors, who're responsible for this, and in fact the Horrors themselves are actually trying to protect the kids. The Horrorland rides might still be terrifying and they are monsters, but it seems even the Menace was too much for them.
- Weaksauce Weakness: Being pinched. Pinching a Horror makes them deflate like a balloon. Subverted in Goosebumps Horrorland, where they're noted as having taken steps to become pinch-proof since the Morris family escaped.
- Would Hurt a Child: In the first two Horrorland books, the TV show, and the video game. The TV show especially points out among the belongings left by the families eaten by Ripper that there are children's toys and baby products. They also seem to actually kill Lizzy and Luke Morris along with their parents. Although in the Horrorland series, they no longer seem to operate like this.
