Windill

Windills are projectile-modifying plants which produce a gust of wind above them to make plant projectiles have lobbed-shot qualities, and also to throw zombies into the air.

Overview
Windill will always create wind above them. When a plant's projectile goes over a Windill, it will fly up into the air. Here it acts as though it was lobbed (it will hit submerged zombies and it can hit zombies on sloped). The airborne projectile will hit the zombies like normal, or however the plant usually aims at zombies.

Projectiles boosted into the air will also have a slight damage increase (+1 damage point). Already lobbed projectiles will still receive this boost, despite the projectile not visually going any higher.

Windill is a low plant, with attributes similar to Spikeweed. Zombies will simply walk over it, and Gargantuars and vehicle zombies will crush it. Zombies that do walk over it will be shot into the air, still moving forward but at a slower rate. Then they will drop down, receiving 1.5 points of damage from the impact.

Wind-affecting plants affect Windill differently. Blover will cause Windill to (permanently) raise zombies higher, now dealing 3 points of damage when they fall, as well as slowing them down further. If Hurrikale is planted on the same row as Windill, the Windill will now increase projectile damage by 3 damage points. These increases do not stack with more plants.

Windill will instantly kill flying zombies if they go over it.

Windill is based off of the herb Anethum graveolens, also known as dill. Its name is a portmanteau of "windmill" and "dill."

Plant Food Ability
Using Plant Food on Windill causes it to bring every zombie on the row to its tile. Then, it will launch them into the air and back to the front of the row (where the zombies come in). This does 5 damage points to the zombies.

Strategies
Windill's damage boost and damage dealing is minuscule, so don't rely on them to take out zombies quickly. Windill's main feature is the altitude increase on plants, meaning that Windill is only really useful on roof-like stages or water stages. This small damage increase also means that you should avoid using Windill on stages where your main damage-dealers are already lobbing plants.

If you are on these stages, plant Windill close to your damage-dealers. This way they get the (albeit small) damage boost and height-increase early. Planting a Windill too far back causes the projectiles to take more time hitting the zombies, especially if the zombies are also close to the Windill.
