Purchasable Plants
These Plants can be bought using Coins as currency that you can collect in game.

Threepeater: $5000 Coins
Threepeater shoots peas in three lanes: the one in which it is planted and the two lanes adjacent to that. Its attack is triggered when a zombie or tombstone appears anywhere within its area of effect (i.e. in any one of the three lanes). If Threepeater is planted on the top or bottom row, it will only shoot peas in two lanes instead of the usual three due to no lanes being above or below its position.

Bacon: $50
