Plantern

The Plantern is used for illuminating the fog on levels 4-1 to 4-9. That's it.

It goes without saying that the Plantern is ONLY useful from levels 4-1 to 4-9

Usage
It costs 25 Sun to place a Plantern. Once planted it clears the fog in radius of 3 tiles, allowing one to see clearly through the mist.

Strategy
Placing a Plantern to the middle-right of the field clears up a lot of the screen. Unfortunately the Plantern is very susceptible to consumption, thus it is prudent to place a Wall-nut or Tall-nut one tile to the right of where one wishes to put a Plantern in order to protect it
