Luke Morris

Luke Morris is the younger brother of Lizzy Morris, whom he thinks of as bossy. Like Lizzy, he is described as having black hair and blue eyes. However, he is more of a thrill-seeker than his more cautious sister. Luke's best friend is Clay. Luke appears in One Day at HorrorLand, Return to HorrorLand, and Escape From HorrorLand as the secondary main character in each book.

One Day at HorrorLand
When the Morris family and Clay get lost trying to find Zoo Gardens, Luke starts pinching Clay and Lizzy to pass the time. Lizzy implies in the narration that this is a habit of his. Although this annoys Lizzy, in the end, his pinching, along with the signs all over HorrorLand, allows Lizzy to discover the Horrors' weakness of being pinched, which ultimately leads to them escaping HorrorLand alive.

In order to solve the mystery of what's happening at HorrorLand during the events of the Goosebumps HorrorLand series, Lizzy and Luke launch a blog to post clues information and information on the HorrorLand theme park. Luke is the main one who maintains and updates the site, although Lizzy contributes to the site in the form of extracts from a "Welcome to HorrorLand" guidebook. Since the site opened, they've received correspondence from Madam Doom, "MONSTER-X", and Slappy the Dummy.
