Out of place

Walking past the large structures which acted as a shield from the suns light. The loud sounds of engines roaring, as wheeled mechanical inventions fly down the roads. Talking and walking was a common sight and noise. All was relatively normal.

Suddenly a scream rings out. People of all ages move their phones away from their eyes, stop walking as well as talking and even cars stop in the tracks. They all stared at one particular individual. A thing that stands out amongst all others.

On the side behind the rails stood a 5 to 6 foot tall being. Black pen structure with a thin body and a head with a face where its stomach should be. It stared back at the people with a confused expression which slowly evolved into a scares one and then into a rage.

The creatures body was outright irregular. A left arm which down from the shoulders become squished or alternatively crushed. Its right arm far more muscular though without any actual flesh or muscle. Its right leg heavily disproportionate and its left leg straight and rigid. Its right eye a cube and its left eye circular in shape with its mouth being triangular.

The creature roared with the might of a squirrel and everything within 50 meters of it became disproportionate including arms, legs, vheicles, buildings etc and a great panic erupted.

After 10 or so minutes the cops arrived, but the creature was gone and evreything else after a little while returned to their original shapes and sizes.

To this day no one understands what the creature was, nor what it was trying to do, if it even had a purpose at all?
