All in Jest

Difficulty: Easy-medium

All in Jest is an achievement in  Plants vs. Zombies 2: It's About Time. To get it, the player must complete a level without using plants that throw projectiles at Jester Zombies, like the Peashooter and the Cabbage-pult. The achievement is worth five points on iOS devices and 500 XP on Google Play Games for Android devices.

Strategies
The best place to earn this achievement is Dark Ages - Night 6. Use Area of Effect plants and Tall-nuts to hold off the horde. Rack up the following before triggering an onslaught: Fill in the backmost columns with Fume-shroom while the second column with Snapdragons. Then finally, Tall-nuts to the third column. Once you have done this, initiate the onslaught and watch how Fume-shroom and Snapdragon do their best. While they are doing this, the first batch of zombies will appear and is composed of three Conehead Peasants and two Peasant Zombies (with Conehead Peasants at odd number columns and Peasant Zombies at even numbered columns).
 * Fume-shroom
 * Snapdragon
 * Tall-nut
 * Anything else to fill

After some time, the squad may step in to the fourth column and trigger an ambush, calling four Imp Monk Zombies and followed by an arrival of two Jester Zombies at the even numbered rows. While the ambush and Jesters Zombies are not taking part yet, fill in the first and fourth row of third column with Tall-nuts to completely block the upcoming zombies off. After some time has passed, sit back and watch the mayhems unfold since the entire level features a fixed attack pattern for the zombies. You may use Plant Food but it is ill-advised since Tall-nuts can survive.

Atl the very end of the level, a final squad that is composed of eleven zombies will appear and there are five Buckethead Peasants, five Conehead Peasants, and one Peasant Flag Zombie. Since there is nothing much needed to be done, have them all get slain by your defenses with you getting the achievement. One note though, with this set-up, you can beat this level without consuming even a single Plant Food.

Trivia

 * All in Jest is a pun on all ingest, which means to absorb all without receiving damage by any mean.
