Danielle the mermaid sat in the back of Susan's car, in a tank which reminded Dan of the aquariums they keep lobsters in in seafood resteraunts. Which, to Dan's distress, was exactly what he- or she- was.
They arrived at a huge house. It was the typical home of a popular (and rich) teenage girl. Susan and Kat carried Dan's tank up to the house and around the back, to a large blue swimming pool. A blonde girl in a bikini, who was Rachel, a close friend of Kat's, lay sunbathing at the side, and she lifted up her shades when she saw the girls come through.
"Hey Kat! Susan! Just set her down in the pool. Don't mind me- in fact, if you need any help, just ask." She had been told what they were doing.
Susan tipped Danielle into the pool, as she began to swim around for the first time. Kat then took out her wand and zapped up some generic beach stuff- shells, sand, seaweed; all stuff that they could use for convincing photos. They could have gone down to the beach, but they didn't want too many people to see this.
"Actually, Rach, you might be able to help us here", said Kat, as she flicked through her spell book.
Rachel stood up and came over. "Sure, anything!"
