I like aliens because I think they are smart and special.
I think aliens have green skin, so they can hide their body in hassock. There are many poisonous spiders and venomous snakes, so they can't eat grass. In addition, they use this trait to hide from plows, when they steal corns and nuts.
I think aliens live on Planet NO.5. There is much land and only a little water. There are a lot of vegetables, fruit, animals, and some many kinds of fish, but no birds. Many fearful snakes and insects live on the planet.
Nobody knows how long the aliens have lived there, because aliens are very arcane and smart creatures.
