She's driving down this muddy trail and gets stuck. She thinks you planned this and are enjoying it, so you might as well sit there and watch her try to get the car unstuck working the pedals with her boots.
Lots of shifting gears to try and rock the car but the back wheels are sunk! She gets out to look at how bad it is and yup, it's bad! She eventually gives up and you two are going to have to walk out of there.

Thanks to Fly for the use of his Flytrap!
