Primal Potato Mine

Primal Potato Mine is the fifth and last plant obtained in Jurassic Marsh. It is the primal version of Potato Mine; it explodes in a 3x3 range and takes only 5 seconds to arm itself, but costs 50 sun instead of 25.

Origin
Like its modern counterpart, Primal Potato Mine is based on the real life potato, the starchy, tuberous root portion of the plant Solanum tuberosum. Its name is a combination of "potato" and "land mine", an explosive device concealed under or on the ground designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks.

Unlike its modern counterpart's, Primal Potato Mine's word on the speech bubble when it explodes is "SPUD OOP!!", is a portmanteau of "spud" and "oop!".

Almanac entry

Primal Potato Mines cost more than regular Potato Mines, but they arm more quickly and do damage over a larger area.

DAMAGE: Massive AREA: Moderate RECHARGE: Sluggish

Usage: single use, delayed activation Range: affects area around it

Primal Potato Mine doesn't consider himself to be primal. As far as he's concerned he's state-of-the-art. And who knows? Maybe he is.

Plant Food
When given Plant Food, Primal Potato Mine will instantly arm itself if not done already and will create two new Primal Potato Mines on two random squares.

Strategies
Primal Potato Mine is a significantly improved version of its modern counterpart, as its positive attribute can easily outweigh the slightly increased sun cost. Compared to Potato Mine's blast radius, Primal Potato Mine's is nine times as large and can cover up to three lanes at once, allowing Primal Potato Mine to control the crowd much more easily as well as destroy obstacles such as tombstones and frozen block. In addition, Primal Potato Mine suffers very little from the its counterpart's arming time problem, and can be planted one space ahead of the zombies with the help of slowing plants. These factors combined makes Primal Potato Mine a highly useful plant both for offense and defense, and a possible replacement for Cherry Bomb thanks to its increased recharge rate.

Trivia
