100WC - The slime dripped through....

We were at school out on the field when suddenly something dripped on me.  I looked up, the slime dripped through the open cloud above.  Where was the slime coming from?  A magical land of unicorns or a UFO circling around trying to abduct me?  We ran as fast as we could to get inside to safety.  Slowly and with caution we peered outside to see what it could be.  SPLASH another dump of slime landed on the ground and covered everything.  Then FLASH a bright light shone and everything went white and a creature appeared from the ship.
