Well in seven years your human brothers and sisters had
gotten married and had kids.So the Alien Diplomatic Advisory Services had arranged for the lot of you all to have a family reunion on one of the giant Mother Ship's orbiting Earth.
You'd gone to the Special Prep shop in the Mother Ship's shopping district and got yourself shapeshifted to a more human looking size and appearance.You now looked like a distant cousin of the gill person race from Centaurious X and on a hunch
it was all going to be a bit strong for your human relatives had asked a clowning anthro weasel you'd met years earlier offworld to come over and do his Clowning Weasel in a Robot Suit act for your reunion in order to break the ice.
And so it was that Willy the "Robotic Weasel Clown" set up his equipment and his three lovely assistants,Lulu the Sea Horse.Ralf the Talking Rowan Tree and Madge the Crested Lizardwoman got the sound equipment ready whilst Willy went over his act with you.
