Attack of the Evil Roommate is the third episode from the third season of the animated series, Martin Mystery. It was originally released on May 19, 2005.
When Martin shows Diana some new "supernatural artifacts" he ordered off of the internet (also in the website, Awesomejunk.com), she barely has time to notice. In fact, she's so overwhelmed with life (homework, clubs, social life, job at the Center), that she off-handedly makes a wish that she could be in two places at once. Later, to her utter shock, she finds that her wish has come true: Diana has a new roommate - herself!!!
