The Happiest City

The Happiest City (also referred to just Happiest City) is the ninth parallel world in Plants vs. Zombies: The Wacky House. The Happiest City takes place at nighttime, allowing the player to use nocturnal plants.
Most levels contain a number of slides on the lawn. Slides occupy a total of three tiles in a row - one for its ladder, one for the entrance to the slide, and another for the slide itself. Players can not plant on the ladder or slide, however they can plant on the tile under the slide's entrance. Zombies will take advantage of slides to make their way towards your home. All zombies will go down the slide almost instantly, regardless of their movement speed, so they will essentially be vaulted forward a tile. Due to the slide's ladder, zombies are not able to eat any plants that are placed under the slide's entrance. Slides cannot be broken.
Also featured in several levels are giant flowers. When destroyed, giant flowers drop 75 sun. Zombies can eat giant flowers, however they will not drop sun when they are eaten or otherwise destroyed by zombies. They absorb 600 . Giant flowers can spawn at the beginning of the level and at the start of huge waves, depending on the level.
The Happiest City's natural counterpart is Gloomy Nights.

== Brain Busters and Minigames ==
=== Brain Busters ===
Two Brain Busters appear in The Happiest City:
*Level P9-4: Special Delivery - Survive as plants are given through a conveyor-belt.
*Level P9-9: Save Our Seeds - Protect the endangered plants throughout the level.
=== Balloon POP! ===
Balloon POP! controls similar to a tile-matching video game, where the player controls a colored balloon and tries to make matches with other colored balloons. The Brain Buster's twist is that grey-colored balloons contain a zombie, and once that balloon is popped the zombie will now be on the run on the lawn. The player can hit the zombie with a balloon, however this will deal no damage. The player must get rid of all balloons on screen to win, except for grey balloons, which may be left alone.

=== Production notes ===
*This world, along with the next, were drawn in a lineless art style. The reason for this is that wanted to experiment and see which art style worked best for the lawns in the game.
