I Almost Drowned in a Chocolate Fountain (Season 1, Episode 3)

Alex decides to cheat on her Spanish test using pocket elves, who have in-depth knowledge of diverse subjects. She cheats successfully and is allowed to go on a date that night with Riley. To get revenge for Alex's snitching, Justin and Max try to plant the pocket elf in her purse, who then bites her, causing her to have Chocoholism (an uncontrollable craving for chocolate).
