Coffee Bean

These Coffee Beans are ready to increase that firepower a bit. These Coffee beans are upgrading plants that will help majorly in the battle between you can the aliens, as they can upgrade Peashooters, spikeweeds, and they can even upgrade the upgrades they already made.

If you're looking for some major firepower, Coffee Beans got your back.

Trivia

 * Unlike in PvZ, the Coffee Bean here does a completely different job, upgrading plants instead of awaking sleeping plants. I mean what else could you do if there's no sleeping plants.
 * As a side note to the piece of Trivia above, upgrades are special to this game and PvZ has none to be heard off besides special plants (Gatling Pea, Twin Sunflower, Gloom Shroom, etc).
