S1·E15 Pushing the Envelope

Bloom finds the answer to a quiz in which they will be expelled is she does not pass; Gricelda takes Bloom on an astral journey to reveal Daphne, the voice in her head. Bloom hides the answers to the test but the other Winx girls try to get them anyway. Flora tries to hide the answers but then returns it to the teacher. Then it realizes the quiz was just a ""pop quiz"" because the envelope ""pops"" when you open it, to see what what happen if you tried to cheat.
