Continuity mistake: While at Dino Stop, Katie convinces her dad not to play it safe and to take a chance to save the world. Rick agrees and extends his left hand for the "all hands, Mitchell family on three." In the closeup we see Katie put in her right hand, but in the wide shot Katie's left hand pulls out. Also, note that in the closeup both Katie's and Aaron's positions between their parents are switched. (00:45:00)
Continuity mistake: Towards the end, before his arrest, Mr. Crystal's fur is messy; it goes back to being clean less than 2 minutes later when he steps on stage.
