Suddenly, the area around the pool changed, from the Thrivesons' house, to the open sea.
he saw the house turn from bricks and tile into rocks and coral, and the edges of the pool faded, revealing the ocean floor.
"What?" William said. HE SAW HIS FAMILY - THEIR HAIR WAS VANISHING, AS WERE THEIR SWIMMING COSTUMES, AND THEY WERE CHANGING, GAINING TENTACLES, AND LOSING THEIR ARMS and legs.
Lisa became a light blue octopus, Olly became a orange one, and Andi became a pink one.
the Thrivesons were no longer a human family. instead, they were octopi.
They were now a 100% pure family of octopi.
All thanks to the The Family Swimming Pool of Aquatic Transformation.
