Worlds
In the campaigns, each world has 20 chapters (except for Brainz Beach, which has 10). The 10th chapter of each world is a mini-boss chapter against Gargantuar or an Upgrade Plant. Completing the battle will unlock the next world and a plant important to said world. If the player chooses to go further, the 20th chapter will be a boss battle against one of Dr. Zomboss's helpers or Crazy Dave. Completing the 20th chapter will reward the player with a trophy. The player must earn all the trophies to gain access to the final world. As in the first game, the worlds alternate between daytime and nighttime.

More to be added.
 * Brainz Beach: The first world of the game, which is an island resort where Crazy Dave and the player are vacationing after the events of the first game, when the zombies attack. Acts as a tutorial for the game, and is quite easy as a result. It is the only world without a boss, and as a result, no trophy.
 * Home Sweet Home: The player and Dave return to the player's home after repelling the zombie attack at Brainz Beach, where it is nighttime and graves return. The boss of this world is Baron Von Bats.
 * Crazy Country: Crazy Dave and the player decide to visit his uncle Crazy Bob's farm to get help against the zombies. Mud puddles appear, which can't be planted on without planting a Sod first. The boss of this world is Old MacZombie.
