Attack of the Mini Aliens from Outer Space

I was walking on a trail with my white Labrador Retriever, enjoying the outdoors. Suddenly heard a loud noise and saw some flashing lights through the trees. My dog started barking, and we went toward the lights and sounds. As we pushed through the tree branches, we saw a large spaceship landing in a pasture. A large door started to open in the spaceship, and suddenly, hundreds of small purple creatures with eight legs started pouring out of the spaceship. They were only about 1 foot tall, and they had no hair, only purple skin and bug-like eyes. My dog started barking at them again, so they turned and started running toward us. My dog and I began to run in the opposite direction. At first, I thought we would outrun them, but then I saw they were surrounding us. They start rushing me, climbing on me, and biting me. So we start fighting this army of small purple aliens. I was throwing them into the trees as they climbed up my legs. I kicked a path through the creatures and called my dog, and we started running again. When I looked back, there were hundreds of the small, eight-legged purple creatures chasing us.
