Fumes

A Fume is a purple cloud used by Fume-shrooms and Gloom-shrooms to fight Zombies. Fumes do one Pea of damage, but hit everything within their range, making them AoEs. Gloom-shrooms fire four times faster than the Fume-shroom. The Fume-shroom has a range of four spaces, where the Gloom-shroom has a range of the eight spaces surrounding the one on which it is planted. The fumes are renowned for their ability to pass through shields like screen doors, newspapers and ladders. Although fume-shooting plants shoot a lot of fumes, they still do as much damage as one pea every time they shoot.

Trivia

 * According to the Gloom-shroom's Suburban Almanac entry, some people think Fumes smell bad. This likely refers to flatulence and not fumes.
 * It should be noted that the Gloom-shroom appears to be holding its breath when it attacks, possibly meaning that even it doesn't like the smell of its own fumes or the gloom-shroom was pushing the fumes out to create 'heavy fumes'.
 * The Fume-Shroom and Gloom-Shroom's Fumes are almost like Spores or just bubbles, so we could say that "fumes" is a term for multiple spores.
 * It is odd that, even though Fume-shrooms hit zombies in their torso, the headwear of various zombies can still block it.
 * Fumes are the only type of projectiles that can shoot up the roof's angle.
 * Because the Fumes seem to be toxic, it´s unknown, how it can hurt Zombies, which don´t have to breathe, as it´s shown in the description of the Snorkel Zombie
