Cat

A small, fast and muscular feline.
Cats were domesticated by humans and are often kept as pets.
Cats are known for their cuteness and how playful they are.
They often seek the warmth and food of Human shelters.
Cats are active at night.

They hunt small mammals and birds. (For example: Rabbits, Mice, and many more.)
Cats have very good eyesight and hearing.

Example 1:
THE CHILDREN: Dad, can we get a cat?
Dad: No.
THE CHILDREN: *proceeds to destroy all of dad's possessions*

Example 2:

A cat sneaked through the dark forest, listening and ready to catch anything that gets in it's path.

Example 3: Just check wikipedia instead of looking this up on the urban dictionary, dumbo.

Ballsniffer

The ballsniffer is the ultimate lifeform. It is as strong as a god, as silent as the night, and is overall just epic. The ballsniffer cannot be described as it is an abstract entity. It changes shape, and adapts to sniff. What does it sniff? Well, anything. But mostly balls, of all shapes, sizes and colours.

The Ballsniffer shall never be spoken of, as it is all-hearing and all-seeing and speakintg of it too much will awaken it. The Ballsniffer has a second variant, named the toesniffe ror feetsniffer. It is just as dangerous, and shall neither be spoken of.

"Ballsniffer" can also refer to the invention of all inventions, known as the Ballsniffer9000. It is said to be hidden somewhere in the world, but no one knows where. Once powered with the souls of young children, the Ballsniffer9000 will do anything it can to sniff out balls. The Ballsniffer9000 looks like an oval shaped, steampunk style device. It was a few small tubes sticking out of it, whose purpose are unknown. The front looks a bit like a microphone, and is where the balls are sniffed,

Lord save whoever dares to spesak of the Ballsniffer.
