A slimy blue thing was in my room.
I grabbed my cat, and looked down at my mat. It was so hard to sleep, so I got up and treaded on my feet. The creature was odd looking. It looked like a pile of pigs mud, but even more gooey and liquidized. This was the weirdest thing I have ever seen in my life. Then, my cat splashed the monster, so I went and reached to turn on my light. I felt silly for having a fright, for it was just my slime that my cat spilled water that made me feel grime.
I can't write the whole summary for you, but writing a summary is quite easy. Just take the main point of each chapter (in your case). Write the main point and what it caused. Kinda like cause and effect. Do this for each chapter. :) If you need anymore help, please feel free to ask! Hope this helps and have a Happy New Year!
