Which in-game guide has plant and zombie descriptions written by Stephen Notley?

The in-game guide with plant and zombie descriptions written by Stephen Notley is the Suburban Almanac.

The Suburban Almanac is an in-game reference guide in the original Plants vs. Zombies. It gives players descriptive entries for the plants they grow and the zombies they face, combining useful information with the series' humorous writing style. Stephen Notley, credited as a writer on the game, wrote these plant and zombie descriptions.

Notley is best known for his work as a Canadian cartoonist and writer, including the comic strip Bobbins. His contribution helped give Plants vs. Zombies its distinctive personality: the guide is not merely a dry encyclopedia, but part of the game's comic presentation and world-building.

The title can be confused with names such as Seed Catalog or Garden Almanac because the game is built around gardening imagery. However, the specific guide named in the original game is the Suburban Almanac. The surrounding game also includes Crazy Dave's shop, Crazy Dave's Twiddydinkies, which is a separate feature rather than the guide itself.
