Continuity mistake: In "Survival of the Hottest" or "Stuck In a RV", the scene after Cat runs to go to the bathroom you will see that Jade and Beck enter the RV and Jade has her sunglasses on top of her head. The scene then goes to Trina and Tori, back to Beck and Jade, Trina and Tori again, then back to Jade and Beck, but Jade's sunglasses vanish. Then it goes back to Trina and Tori, then Beck and Jade and the sunglasses are on her head again.
Other mistake: Robbie gives Tori a chocolate leaf-blower as a present to cheer her up. Then when Robbie leaves to go join Cat at the Platinum Music Awards, he supposedly takes his chocolate leaf-blower present with him. But, in the shot where he leaves Tori's house, the bag that the chocolate leaf-blower was in is still on the floor.
