Road Trip was the main mode in Plants vs. Zombies Adventures. In it, the player went through levels using plants to defeat zombies. At the end of all stages except The Boonies and Zombitorium Manor, Officer Ron would have appeared as a roadblock. Getting past him would require paying a certain amount of gems to hire people, or asking the player's friends to help them with their road trip.

When the player is in certain level, Crazy Dave would have given a challenge to the player in few levels. The challenges had two types. The first one was that Zombie Fog covered the area, and the player could not see the map clearly. Another one was that Crazy Dave picked plants for the players, but the max limit of plants was increased as well.
