Factual error: When Snowflake is being stolen at the beginning, he makes the high-pitched noise that dolphins make even when he is out of the tank; those high peals are made underwater through carrying sound. He wouldn't sound the same out of the water as he did under it.
Factual error: The movie that Ace plays back when he goes to Finkel's house mentions that it is Superbowl 17.
