Ring of Fire

The Ring of Fire is a sunflower that will automatically collect falling sun for you as well as explode when eaten.

Usage
This is an usual type of sunflower that will not produce sun. However because it collects sun that falls almost instantaneously and automatically. This allows you to collect sun while focusing on more important things. In addition to this, which ever zombie should eat this, will be instantly blown up but doing no splash damage. However, this sunflower is not efficient enough to only serve as an instant kill for zombies, because it only kills one, and the sun cost and packet recharge is too slow and expensive for being one.
