However, something's fishy when a strange sea virus threatens the local aquatic population.

The young witches must find a way to help the doomed sea creatures and at the same time, protect the secrecy of the mer-species...

Sabrina is thrilled when Salem tells her that her aunts are going to get her a cell phone. Then she discovers that Salem was playing a trick on her, so she checks her magic book and finds an offer for one, complete with service contract for a week's trial. But there's a catch. Every time Sabrina even slightly crosses the line between right and wrong, the phone rings. The contract can't be broken, whenever she tries to 'lose' the phone it finds its way back to her, and all that ringing is driving her crazy. It takes a while, but finally Sabrina gets the message.

Sabrina must add a physical education class to her college schedule and chooses beginner's horseriding. Unfortunately for Sabrina, she is assigned to a cranky and lame horse called Mission Impossible. If Sabrina cannot successfully learn to ride Mission Impossible in the next two weeks, she will lose face in front of her snobby classmate Debra and, even worse, Mission Impossible will be sold to a run-down holiday horse company. Staying on a horse is hard and learning to ride overnight is a mission impossible so Sabrina uses her powers to become a more competent rider. However, when Sabrina enters a riding competition she cannot use an ability spell or ride a magically enhanced horse. Now Sabrina can only hope that together she and Mission Impossible can use their own skills and strengths to win.
