The objective of this mini-game is relatively simple: the player needs to stop the zombies by launching Corn Cobs, but he or she can also temporarily stop zombies by placing Butter on their heads. The player can use his or her fingers in a smearing action on the touchscreen to immobilize large numbers of enemies, rather than tapping the heads of individual zombies. It is also worth noting that if a Cob Cannon is eaten, it cannot be replaced, and there are no Lawn Mowers or Pool Cleaners to protect the area against the zombies that will inevitably get by. The most difficult zombie on this level is the Dolphin Rider Zombie, as it moves at high speeds, and, as such, hard to stop with butter. Whenever the Gargantuar is in the third column, the player should not shoot a Corn Cob at him immediately, as he will toss his Imp. Instead, he or she should stun him with butter to prevent this from occurring. The player can also stun his Imp before it eats a Cob Cannon. If the player still cannot beat this level, the player can use two people instead of one (one person could control the Cob Cannon and one person could butter the zombies, etc.). The player can also fire two Corn Cobs at once and targeting the two land lanes closest to the pool so that zombies in an area in all rows will be hit.
Note: The * indicates a zombie that only appears upon restarting.
For some reason, Buttered Popcorn is a Pool level, despite no aquatic plants being used, but this may be so that players can only have four Cob Cannons, or so Dolphin Rider Zombies can appear, making the game harder.
This is the first Mini-Game exclusive to a particular version of the game.
When the zombies eat all Cob Cannons, the player can't kill any more zombies, inevitably causing the player to lose.
Despite the game being called Buttered Popcorn, the player cannot earn the Popcorn Party achievement in this minigame, probably because it would be too easy, and because there is only one Gargantuar. There is a chance that the player may see two Gargantuars in the Mini-game. The player can earn the achievement, but he or she has to purchase the Cob Cannon first.
There is a glitch where if the player restarts the game over and over, there will be no Gargantuars.
Like the mini-game Last Stand, there are no Lawn Mowers or Pool Cleaners.
The only other trait these mini-games have in common is that they are both version-exclusive mini-games. (Air Raid is only found on the Nintendo DS version, and is not to be confused with the cancelled mini-game of the same name.)
