September 22: A Witch's Tail, Part 1 and 2: The fifth season opens with a splash as the witchy women aid a forlorn mermaid in back-to-back episodes. Mylie is the "little mermaid" who finds herself in hot water with a sea hag after making a deal that transforms the marine creature into a human so she can search for true love. But Mylie has only 30 days to find Mr. Right and have him declare his feelings for her, or she forsakes her immortality. Unfortunately, she loses her heart to a man who is reluctant to express his emotions and it's up to Phoebe, Paige and Piper to persuade him to open up. Piper's pregnancy brings extra problems as she suffers from ill-timed panic attacks.

September 29: Happily Ever After: A wicked witch escapes from her confinement in a magic mirror and sets out to vanquish the sisters by using enchanted props from various fairy tales. Meanwhile, Piper conjures up the spirit of her dead grandmother for advice on how to prepare for her baby's birth.
