One hot bitch...but she is a lazy fat one at that! When disturbed approach with extreme caution for she will move with the grace of a walrus. She wears clothes that are too tight and revealing, but still reveals her extreme hotness.

Once a year she moves to the outside world for migrating season. This is a very emotional time for a shelly as it can only find one brad out of hundreds. Once she has found her brad she then mates and moves back to her final resting place. 2 years from that time a small fetus grows inside of her until she releases it into the milo tin where it slowly sheds its powderised liquid crap which form the weak as shit milo.
Look at that Shelly, what's it doing with that milo tin?

A wonderful girl. One that knows the right things to say to make you smile, even when you are at your lowest. A girl who you'd want to make smile just because her smile is one of the most beautiful ones you have ever seen. Her personality is bubbly, and she is a bit weird. Her laughs and giggles are contagious since it will get everyone laughing too. She is one of the most beautiful beings in existence.
Person One: What's the name of that star there? It's really beautiful.
Person 2: I know, it's almost as bright as Shelly.
