Leechee

Leechee is a plant in Plants vs. Zombies 2 that was introduced in the 8.3.1 update. When it makes contact with a zombie, it will latch onto it and damages it overtime. Once it has killed the zombie, it will turn into a seed packet which you can place anywhere.

Once replanted, the Leechee will act like a Wall-nut, albeit with the health matching that of a health of the zombie it has sapped. (i.e. sapping a Zombie, which has has 200 damage per shot, will let the Leechee take 200 damage per bites.)

Leechee requires 250 seed packets to unlock for free. The player can do so by replaying Modern Day to earn Piñatas from the piñata tracker.

Origins
Leechee is based off of the Litchi chinensis, also known as the lychee, and the leech. Its costume and flavor text is a reference on how plague doctors used leeches as a form of treatment.

RECHARGE: Mediocre

Leechees suck the health out of the zombies they sap, and turn that health into his health.

"I've had my time dealing with the plague." said Leechee. "I've met a lot of doctors, and I surely was impressed by how they treated their patients. There's no way their methods didn't work!"

Strategies
Leechees are capable of being useful, however it heavily depends on which zombie it decides to sap. Sapping a regular zombie will render the plant to be quite useless, due to it only being able to take 200 normal damage bites at that state. It is heavily recommended that it saps onto armored zombies such as Coneheads, Bucketheads, Brickheads, and even Gargantuars. While it will take a lot of time for a Leechee to sap these zombies due to their high health, the pay-off is heavily worth it, with the Leechee potentially being stronger than the regular Wall-nut or even the Tall-nut as a result.
