Hall of Infinite Doors

You are a 27 year old working at as a software engineer for a respectable company. It is your day off and you had planned on sleeping in. At noon you are awaken by an unfamiliar voice. You look up and find a blue fairy with combat boots and a machine gun staring down at you. She says, "Wake up you lazy maggot. No more sleeping in today. You have to get over to your neighbors house. In his basement is a secret lab. In that laboratory is a creature. This creature is going to continuously evolve and grow more powerful as it does. The longer you wait the more powerful it will become and soon it will grow strong enough to destroy the world! Head over right away and destroy it! Do not procrastinate or the world is doomed! I would do it myself but I have an appointment at the Spa. Good day."

With that she dissapears. You slap yourself to check if you are awake and realize that you definitely are. You get out of bed and get dressed. At this point it is 12:15 PM. What will you do?
