Leland

Leland is Rowley's next-door neighbor who is obsessed with the role-playing game Magick and Monsters. In Rodrick Rules, much to Greg's surprise, Leland replaces Heather Hills as Rowley's babysitter.

Rodrick said in Rodrick Rules that Leland is the biggest nerd in his high school.

His last appearance was when Greg announced the winner of the school's talent show in his diary. Greg states that even though everybody thought Leland stunk, he won the grand prize for an act of ventriloquism, which the judges thought was "wholesome."
