A gremlin clinging to the outside of a vehicle suggests the famous Twilight Zone episode, Nightmare at 20,000 Feet.
The title sounds like Are We There Yet?.

The second mystery however prints with a red herring and an unexpected solution hinted at during the beginning. Joe Staton of course does a smashing storyboard.
