Sun cost: 600
when you place down a soap-wart root, it waits until its next to water or a fire plant. it then turns into soap and covers the tile in soap. the first zombie to slip on it will turn upside down. the zombie becomes basically a tall-nut when stuck. when the soap-wart root is not soap, if a zombie eats it, the zombie gets so clean the light reflects off them, and then the zombie burns, giving you 100 sun.
