Exeggcute

{1}{b}: Exeggcute gets +0/+1 until end of turn.
Leech Seed (Whenever this creature deals damage to a Pokemon, you may put a leech seed counter on it. At the beginning of your upkeep, you gain 1 life for each leech seed counter on Pokemon your opponents control.)
Even though it appears to be eggs of some sort, it was discovered to be a life-form more like plant seeds.
