Revealing mistake: The scene where Macduff, Johnson and Diesel are happy because they found Macduff's "button" medal of bravery, watch when diesel jumps up and down. You can the actor's black shoes he is wearing. This also happens throughout other parts of this episode.
Visible crew/equipment: In the scene where Mcduff and Johnson are trying to find water since it's extremely hot, they go under the bed and notice Alfred under there. Look in the background, for just a split second, you can a man walk past the from the door. It's for only a split second so it's quite easy to miss.
Continuity mistake: After Michael's tooth falls out, the toys go to clean it. When they accidentally squeeze the toothpaste on each other, it finally shows Alfred holding up the toothbrush correctly because Diesel can't seem to, Alfred's appearance is short, dark green and smaller in size. But then Johnson appears and says "I'm going to remove this toothpaste tube before it causes anymore damage" the shot cuts to Alfred with the toothpaste squeezed on him, and his appearance has changed; with a larger head, bright green body and larger in size. A few shots later, he is back to his original form.
