Coffee Bean

Coffee Bean allows the player to use mushrooms during the day by waking them up. To use it, place the coffee bean on a sleeping mushroom.

Strategy
The mushrooms are very cheap, but 75 Sun is a lot to pay to wake them up. These are only useful with special mushrooms, like the Magnet-shroom, the Gloom-shroom, the Hypno-shroom, the Ice-shroom or the Doom-shroom. Another useful tactic to plant a couple of instant-effect mushrooms if you know you'll need them later, and pop a Coffee Bean on them when you need the effect. This successfully eliminates the packet recharge because if you plan it right, you can use a pre-planted mushroom and a current mushroom back-to-back.

Good Morning Achievement
In order to get the achievement Good Morning on the iPhone/iPod Touch/iPad version, Coffee Beans are crucial as the only other plants you can use are mushrooms. The falling Sun from the sky helps to ready the Coffee Beans, and once you have a sufficient amount of Sun-Shrooms they will help generate the sun to wake up the Scaredy-shrooms and Fume-shrooms you will use.

Trivia

 * The Coffee Bean, Plantern, Lily Pad, and Flower Pot are the only plants with no offensive or defensive abilities.
 * The Coffee Bean, Tangle Kelp and the Squash are the only plants that cannot be eaten, although the Tangle Kelp and the Squash can be killed by basketballs, Jack-in-the-Box Zombie explosions and peas from ZomBotany Zombies. Note that Jack-in-the-Box Zombies Gargantuars, Zombonis, Catapult Zombies and Squash Zombies can destroy Coffee Beans than any other zombie could.
 * As can be seen by looking at the Coffee Bean's Almanac entry, the Coffee Bean levitates. This is likely because it is planted on top of a mushroom so it must be above the ground. The Coffee Bean also levitates in the Zen Garden, if you have it.
 * On the Game of the Year Edition box cover, the Coffee Bean has wings.
 * When the Coffee Bean is used, it will be like coffee powder.
 * When you use a Coffee Bean at a sleeping mushroom, the mushroom will stretch a bit.
