Light
Buttercup mewed. The walls shaking and the loud noises were scaring him. Prim cuddled him in her arms. She always made him feel better. Suddenly, there wan't any warmth where Prims arms should be. He hissed in contempt for the whole situation. Suddenly, a dot of light on the wall caught his eyes. He batted at it in curiosity. The light moved.
What the devil is going on here? Buttercup thought. (As you're reading this, imagine Snape's voice from AVPM)
He lunged for the light, hoping to entrap it in his paws. Success! But wait! The light was on top of Buttercups paws. Is this some type of luminescent insect?
Buttercup prowled towards the phenomenon that he had discovered. He flicked his tail in anticipation of the catch. He leaped towards the light, pinning it under his paws. He slowly lifted up his paw to observe this light, but the light wasn't there. Buttercup searched for it until he saw it resting on a human foot. Prims foot.
Prim was holding a metal stick with a light at the end. She was surrounded by laughing people. They were all looking at Buttercup. Buttercup made his tail stick up straighter and flicked his ears up impressively. He needed to look good for all these people. He strutted over to where the light was sitting. Maybe, if he acted as if he wasn't interested in the light, the light wouldn't move. When he was a foot away, Buttercup pounced on the light. He let his claws out to better capture it. But the light moved away again.
I will get you eventually, Buttercup thought, and then he lunged for the light.
