beginnings

I had an idea for a story the other night that I'd like to play with a little, so the following is some brainstorming about said story...

Fred just arrived in town. As a matter of fact, Fred just arrived on the planet. His real name isn't Fred, of course. He adopted the name after landing and observing the people he found on Earth. Fred's spaceship landed in a field beside an Ikea in the midwest. He was lucky enough to arrive the night before the store's grand opening, so he was able to see many earthlings as they came and went. He wanted to join them in their excitement, but Fred could hardly pass as human. He didn't look like the tradition alien, though. He wasn't green with a huge head. However, he was short and very round with spindly little legs. His head was proportional to his body, but domed rather than round. His skin was iridescent and reflected sunlight, so he could not venture out during the day. But Fred wanted to know as much about this planet as possible. He accidentally discovered that he could tap into satellite television feeds, so he spent many days watching and learning until eventually he learned English. He saw a commercial in the middle of the night advertising a local sci-fi convention. The ad showed many people dressed in costume to represent television aliens. Instantly, Fred knew this was his way into Earth's society. He could go as himself. Who would question one alien in a crowd full of aliens?

I know it's not pretty, but I'm just brainstorming. Maybe someday I'll actually do something with it.
