Continuity mistake: When Corrina leaves Molly's house for the first time, we see her pick an orange off the tree and walk away. She then turns around and tosses the orange to Molly. The next shot of Corrina shows her walking away with another orange in her hand. She only picked one, and threw it to Molly.
Visible crew/equipment: While Manny heads out for his meeting with Mr. Potato Head he overhears Molly playing the piano with Corrina, and when it cuts to Corrina in Manny's bedroom flipping the white bedsheet up in the air, a crew member's arm appears and disappears at the left side of the screen.
