My dad use to tell our family stories about how if we put a cookie and a glass of milk out at night it would bring good luck kind of like cookies and milk for Santa Claus. I didn’t really believe it but I thought it was funny so I always did it anyway. My first thought was my dad was just eating the cookies and drinking the milk. This tradition went on for years and I never questioned it, it was a part of my weekly routine now I just did it without realizing it. But one day my little sister got into an argument with my dad and she said “you know what who cares about your good luck cookie” and smashed it with her fists. After that, we each headed towards our room and went about our business. I was gonna replace the cookie but we had run out and our dad said he was going to buy more later.
Little did she know that wasn’t just a good luck cookie. What my father had failed to tell us was that it was actually protection from what would come if the cookie was destroyed. Soon after it was destroyed all of a sudden the atmosphere turned grim and you could tell something was off. Someone was in the house that we didn’t know. I noticed a little blue figure but thought it was just my imagination and went on with my day. All I could hear from my room was a faint voice saying "Cookie" which got louder and louder by the minute. I ignored it at first since I was in my room playing video games and didn't want to bother with checking.
Soon after I heard my little sister scream I rushed to the kitchen and saw my sister getting chased by a little blue monster. At first, we thought nothing of it thinking it was my dad pranking us, but we thought about it and there was no way my dad would be able to pull that off. Then soon after we saw it, that little blue monster we thought was a joke carrying a knife and then it suddenly disappeared. With nowhere in the house to hide all we had to do was hope nothing would happen and call for our dad, but he was out for the night along with our mother. We looked around the house for spots to hide and we tried leaving outside to go to our neighbors but the doors were slammed shut and impossible to open as if there was a magic force holding it closed. Scared for our life we tried looking for weapons but everything in the house was gone. The only thing we would hear was a voice saying "cookie" that got closer and closer but we couldn't see anything. We didn't hear the voice for 30 minutes so we assumed everything was safe but little did we know that once we left our spot he would be waiting.
Soon we were found by what we named the little blue monster, The Cookie Monster along with his weapon seeking revenge for his broken cookie.
