The player will have control of a Lawn Mower with a peashooting plant on it where they will have to shoot all of the zombies. They can upgrade the Lawn Mower permanently into a Repeater, which will make it shoot peas in two directions, to a Threepeater, which will make it shoot in three lanes, and then to a Cattail, which will then make it shoot homing spikes and can purchase two times more to shoot faster. Additionally, the player can buy a Torchwood, which will temporarily make all the player's peas fiery, a Doom-shroom, which the player can use normally, and a Snow Pea, which will temporarily make all the player's peas frozen. Also, any sun, coins, diamonds, and presents uniquely must be collected by the Lawn Mower.
A Doom-shroom does not need a Coffee Bean to wake it up even though it is a mushroom, and the mini-game is set in Day. In this mini-game, Doom-shroom costs 200 sun, which is the total cost of a Doom-shroom (125 sun) and Coffee Bean (75 sun) during the day.
When the player pays for the Doom-shroom, the explosion will always be in the middle of the screen. The player can use the Doom-shroom even if the crater is still present.
This is possibly because the level might be harder if the player couldn't plant it on the crater.
