Sonic-shroom

The Sonic-shroom is the fifth plant obtained in The Moon. Sonic-shrooms charge up to send a sonic blast down their lane, dealing heavy damage to all zombies in the lane and pushing the first three zombies back one tile. Sonic-shrooms will suck in enemy plasma up to one tile in front of them, becoming supercharged for a short period of time. While supercharged, the Sonic-shroom charges at double the rate.

Suburban Almanac Entry
Sonic-shroom is one of a rare faction of plants devoted to the practice of psychic resonance. “With a focused mind, I can make sound anywhere. I can even send sound through space. You just watch me!”

Strategies
Sonic-shrooms are essential for use in The Moon as a counter to the plasma attack of Fugitive Zombies. Sonic-shrooms can absorb Citron’s plasma reflected from Jester Zombies. This could allow the use of the Citron as an attack plant in Dark Ages with Sonic-shrooms in the front row or second row. Of course the Sonic-shroom itself does not fire projectiles, so is itself immune to the Jester's abilities.

Sonic-shrooms can be placed either in the front row or one behind the front row, so that they can be placed behind defensive plants. However, on the moon, a full row of sonic-shrooms and defensive plants is not possible due to the limitation imposed by the moon and Vac-shrooms. The knock back of the Sonic-shroom should be helpful to keep zombies from reaching the frontline without defensive plants. Also, the Sweet Potato could be used to overcome the problem.

Trivia

 * The Sonic-shroom appears to suck in air before its attack.
 * When supercharged, the sonic-shroom has a white glow.
