It happens on this time of the year. The deadly plants from another galaxy starts to fall, in an attempt to change our world. Change it to what? Change it to become livable for their evil alien masters, the inhabitants of Snøtopia, also know as the Snøfilius Sapiens. They live no a distant planet, in a galaxy far far away... Sorry, couldn't help myself. Anyway, our planet has been chosen as the suitable target for expansion of their race. You see, earth is one of few planets which are livable, and which also come down to the fitting cold at times, which their plants of evil can live. As a matter of fact, their planet, Snøtopia, is made entirely out of "Snø". Or snow, as its known in the common tongue. This is why the strange inhabitants of this planet require it in order to live.
Although, as most people know, this attempted invasion fails every year, due to the changing of seasons. This assault has been continuous over thousands of years, but the invaders refuse to give up. The source of this plant are portals of a sort, spread throughout our galaxy, and its through here the snow is siphoned. Do note that the "Snø" itself is not harmless, but rather quite dangerous. Every snowflake is in fact a seed, each of which is capable of draining whole patches of fresh earth of it's natural power of life. Of course, this planet is yet by far too hot for this to happen, and it takes a lot of seeds to do any permanent damage.
There is, on the other hand, a way to fight these plants, and their masters. You see, there are a fatal material here on earth that kills them just by being near them. This particular material is contained in a normal household object, batteries. That's right, the small cylinders you use to power your TV remote also holds the power to defeat alien forces of unknown magnitude. It's quite easy actually, you just keep a small amount of them in your pockets, and the Snø in a small area around you falls dead, unable to do harm. I would strongly suggest everyone to keep some batteries with them at all times, for the good of your planet!
So. Now you know. Now you know what those ghastly things are, and you know how to fight them. Rejoice, and help your world today! For further questions, and advice, please contact me in the comments below.
