The Attack of the Sphinx.
Episode Description:
In Egypt, the Winx defeat the mummies; Selina then calls up the Sphinx to attack the Winx and the city of Alexandria. Meanwhile, Acheron (a powerful sorcerer trapped within the Legendarium who is Selina's mentor and master) tells Selina to seek out the diary from the library, or else he'll be locked in the book forever. While fighting the Sphinx, the Trix (disguised as Alfea fairies) cause chaos, but the Winx and Pixies resolve it. Bloom goes to find the diary in the library, which she does. To her surprise, she also finds Selina, who is revealed to be an old childhood friend of Bloom's when they were kids.
