Gunicorn 

That super rare, legendary item (in this case a gun or firearm) in any First Person Shooter or Looter Shooter type videogame. This item can instill the finder with a great level of "gear fear" to avoid loss of epic item. As one tends to die with newly acquired weapon shortly after finding one.

Player 1: I found an M82 fully kitted!
Player 2: A mythical Gunicorn?!
Player 1: (nervously)I'll see you at basecamp while I hoard this one away.

Ganicorn 

Ganicorn is the biggest, baddest gorilla on the planet. He's an amazing cuddler and very lovable, even though he has a scratched left eye and lopsided features. He also really needs a haircut (NOT from Supercuts).

Girlfriend: Ganicorn is so amazing! I can't fall asleep unless I'm cuddling with him....
Boyfriend: I'm going to f*cking kill Ganicorn!
