W.I.T.C.H. - Season 1 Episode 15 The Mudslugs

Elyon seems to have adjusted to her new life as the Princess of Meridian, living in Phobos' castle, although she is still under the illusion that Phobos has created. Meanwhile, Cornelia gets so upset about losing Elyon to Cedric and Phobos that she quits being the Earth Guardian. Phobos uses this to his advantage and changes the image in the sand to make it look as if Cornelia is getting along just fine with the others and not missing Elyon at all. Phobos sends Meridian Mudslugs after the remaining Guardians and without the Earth Guardian. When they realize that Cornelia is the only one who can defeat them, Will uses the Heart of Kandrakhar to tap into the broadcast frequencies to reach her. Cornelia saves the day by telekinetically levitating the huge mudslug near the portal. She is now officially back in the W.I.T.C.H. group.
