Pistackio

Pistackio is a plant that heals plants in a 3x3 area. It can be bought for $11,000 in Wall-nut Mart.

Effect
As many Pistackios as you like can be planted on a single square. 30 seconds after the first one on the square had been planted, all the Pistackios on that square explode, healing all the plants in a 3x3 area by 1 NDB per Pistackio. They absorb 4 NDB each (EG If there were 5 Pistackios on a square, altogether they would absorb 20 NDB). If one of the Pistackios is eaten, it will take away 1 NDB from how much the plants in a 3x3 area will be healed by. If there are 6 or more Pistackios on a single square, zombies won't be able to vault over them.

Almanac Entry
Pistackios' insides are shaped like tables, allowing them to stand on eachother with ease.

Trivia
Pistackios are based on Pistachios.
