Milkcap

Milkcaps are sun-producing mushrooms that make more sun when zombies are on the terrain it places down.

Overview
A Milkcap usually produces 50 sun at the rate of a Sunflower.

When the player plants a Milkcap, it will summon mushroom colonies around it. These colonies go for 5 tiles ahead of the Milkcap, 1 tile behind it, and 1 tile above and below it. If there are zombies on these tiles, Milkcap will produce more sun. For instance: If there is a Gargantuar on its colonies, then it will produce sun faster.
 * 1 zombie = 75 sun
 * 4 zombies = 100 sun
 * 8 zombies = 125 sun
 * 15 zombies = 150 sun

If Milkcap is in daylight, it requires 1 more zombie for each increment of sun.

Plants can be planted on its colonies, but the player will need 10 extra sun to plant a mushroom on the colonies.

Plant Food Ability
Using Plant Food on a Milkcap will make it so that the colonies slightly slow down zombies. This also negates the extra sun needed to plant mushrooms on the colonies.
