Escape Root

Escape Root is a premium plant in Plants vs. Zombies 2, tied with the Modern Day Part 2.

When planted, Escape Root will take 10 seconds to arm itself before emerging, and afterwards will transform into either a Potato Mine, a Cherry Bomb, a Grapeshot, or a Primal Potato Mine upon contact with an enemy. The player can also switch Escape Root's place with another plant's simply by tapping Escape Root, then the plant the player wishes to swap; doing so will also instantly arm the plant. Escape Root is classified as an underground plant, and therefore cannot be planted on, or switch place with plants on water tiles in the Big Wave Beach, or on the planks in the Pirate Seas.

Origins
Escape Root is a pun on "escape route".

Almanac Entry
Escape Roots explode on contact, and can be swapped with other plants that are in danger.

Special: tap Escape Root and another plant to swap them

The other plants put on a big surprise party for Escape Root last week, but he did his thing and suddenly it was a surprise party...FOR THEM!

Plant Food effect
When fed Plant Food, Escape Root will summon two Escape Roots next to a zombie one at a time that will turn into a random explosive.

Strategies
As the own name says, this plant can be used on some levels where you have to protect endangered plants, simply by swapping place with them. You can use Sweet Potato to gather many zombies at a single place and later swap place with this plant in order to instantly destroy the zombies. It's more accurate eficiency if the zombies are all in a single square, since the explosion range of this plant is not much trustworthy.

Trivia

 * There is a glitch where Escape Root do not spawn an explosive plant when a zombie is near. Instead, just as when it has not armed yet, it gets chewed on.
 * This is the third plant which can turn into another plant, with the first one being Imitater and the second being Intensive Carrot.
 * If you use Plant Food on an Escape Root when there is one zombie on the screen and there are no other zombies after it explodes, the boosted Escape Root will spawn an Escape Root on itself. After it explodes, the Escape Root's dirt cannot be seen.
