Waterfall Entrance is the first leg of the route after the plants leave the street east of the house and enter the Maple waterways.
World-map dialogue points toward Maple Falls; damp air, stone paths, and autumn scenery already establish the mood of Maple Mountain.
The water here is calmer than at the main falls, but flowing channels already divide the battlefield and the path has begun to climb.
As the opening leg of the voyage, it carries the defense beyond the lawn: the plants must adjust to wet ground, waterfall winds, and the first local zombies along the route.
